The Esplanade of the Castle consists mostly of wide sidewalks and very large spaces without attractive elements that encourage permanence and appropriation. These areas are located in the Environmental and Cultural Protection Area (APAC), Cultural Corridor A2 (figures below), in the city of Rio de Janeiro, where the city hall has been providing guidance on actions to contribute to the formation of the city's memory.

Transform the routes with few attractions—due to the limited offer of services around the remaining block—into a buffer zone, by exploring the importance of this area through the green network (trees), an element that resists and persists amid the constant transformations of the landscape.
The device aims to promote balance and the regeneration of urban center pathways through attractive sound atmospheres that simultaneously respond to two time scales: cultural processes and natural processes (such as the slow migration of birds). The system favors ecological dynamics over static constructions to enable the cohabitation of humans and animals within the city.
Attractive sound atmospheres are composed of birdsong. In addition to contributing to the remaining ecosystem by “inviting” other pollinating birds and songbirds (those with melodic calls), the birdsong also helps to create a more mysterious and seductive place.
The goal is for the sound route to stimulate visitors (both national and foreign) to reinterpret the green network and historical buildings—elements that resist and persist through the continuous transformation of the landscape. Birdsong represents a form of communication that does not conform to rigid discourse systems, and is capable of leading us to a heightened awareness, beyond the surrounding noise pollution, while paradoxically allowing us to detach from it.
Location: Jardim Botânico neighborhood. Rio de Janeiro-RJ
The Swallow-tailed Hummingbird (Eupetomena macroura) was chosen as the protagonist of the system due to its presence in urban areas of southeastern Brazil, its importance in the pollination of plants, particularly in South America, and mainly for the possibility of the device transforming its pollination habits (input) into sound actions (output).

Transformation of the scissor hummingbird's pollination habit (input) into a sound action (output). The prototype exploits the bird's ability to approach hundreds of flowers several times a day to feed on the nectar. In addition to "inviting" other birds with melodic songs and pollinating birds, the reproduction of bird songs (sound action) will also amplify the ability to sensitize human beings (the song of the scissor hummingbird does not sensitize human beings because it is not a melodic song).

Mapping of activity points in the Castelo-RJ neighborhood at different times during the working day (Points of attraction). Times: start of working day, lunchtime, end of working day, evening.
In the isometric perspectives, we can see the vertical lines that indicate key intersection points resulting from the overlapping of the data of the activities that are in operation at the same time. In other words, the agglomeration of vertical lines indicates places with the greatest flow and/or concentration of people during each time slot under study on a working day.

To check that the analysis of the points of attraction corresponded with the reality of the place under study, I visited the Esplanade do Castelo at least once a week for three months. To facilitate my interpretation of the city, I used five basic elements defined by Lynch (1960), which are: paths, boundaries, neighborhoods, nodal points and landmarks. ( Mind Maps )
This process confirmed that the points of attraction really do exist and uncovered more points. The crosswalks on Avenida Presidente Antônio Carlos are points of attraction, as they guide flow of walkers on certain stretches of the Esplanade do Castelo. The result was a map showing fluctuating active population during the working day and the proposed route for intervention on the Esplanada do Castelo-RJ.
All the points of attraction were connected by Avenida Pres. Antônio Carlos, as this is the road with the greatest flow during the working day. This group was called the floating active population plot.
The map shows the floating active population plot resulting from the overlay of the service offer maps over the course of a working day ( in Purple ) and the route of the landscape design intention around the remaining court ( in Pink ). It can be seen from the map that the remaining block does not have enough attractions to be part of the floating active population's route. The points of attraction ( in white) are located at: Praça Mercado Municipal , Praça XV , Praça Mário Lago , Av. Eramos Braga , Rua Santa Luzia (in front of Santa Casa) , Av. Churchill , Av. Franklin Roosevelt , Intersection Av. Ântonio Carlos and Av. Beira Mar , Museum of Modern Art.

Sensors involved in walking
It consists of associating three aspects that generate five linear diagrams: the kinaesthetic experience, the visual experience and the auditory experience to analyze the route of the walk.
This methodology gives us a quick and relatively explicit understanding of the experience of walking certain routes..
Lawrence Halprin was one of the first to point out the need to describe the movement of the human body in space for analysis and project development with his book Cities, Space for walking . Between the 1960s and 1970s (the height of the counterculture) Halprin developed holistic practice in his projects, always taking into account bodily expression, urban culture and local nature as a response to the collapse of coexistence in the modern (post-war) city with the pre-existing context. His methodology consists of developing diagrams using a personalized ideographic system to describe the walk in an abstract way with small annotations that correlate with each other.
WALKING - visit to the Residual Spaces around the remaining block of Morro do Castelo -
Residual Space 01 / partial panorama photo / Rua Santa Luzia Centro-RJ, space underused as a parking lot. Potential _ Space with a predominance of medium to large trees (Figueira-Religiosas proposed by the landscape engineer Auguste François Marie Glaziou) and a beautiful view of the façade of the Santa Casa da Miseridórdia.
Residual Space 02 / stereographic photo / Praça Antenor Fagundes - Centro -RJ , space underused as a parking lot. Potential _ This is one of the areas where the remaining square intersects with the built-up square (after the landfill process), where passers-by have the greatest perception of the rupture in urban thinking on the Esplanada do Castelo, as it is reinforced by the different roads and types of buildings.
Residual Space 03 / partial panorama photo / The wall of the parking lot of the Ministry of Finance - Centro-RJ, an underused and inaccessible space on Rua Marechal Aguinaldo Caiado de Castro. Inhospitable and silent area around Praça do Expedicionário, reinforced by the mono-functional and homogeneous character of the Judiciary Complex. Potential _ Large space and cradle of the formation of the city of Rio de Janeiro-RJ (formerly Morro do Castelo-RJ).

Remaining Pavement that led to Morro do Castelo (demolished in 1921 to modernize the city)
Ladeira da Misericórdia, the last remnant of Morro do Castelo, was listed by the National Historical and Artistic Heritage Institute (IPHAN) on September 27, 2017. The slope is next to the Nossa Senhora de Bonsucesso Church, the oldest church in the city. The site was the main access to Morro do Castelo. It was an area of 180,000 square meters that was Rio de Janeiro's first urban center. In its early years of occupation, the hill was a fortified site to house the Portuguese and resist any attempt by the French and Tamoios to invade. It then housed low-income families until it was destroyed. Source: portal.iphan.gov.
Floor plan of the Esplanada do Castelo - RJ with the proposed landscape design for the surrounding area of the court remaining after the dismantling of Morro do Castelo. Developed using Revit software+ Rhinoceros / Grasshopper.
The integration of the existing cycle path into the proposed project is essential to guide active mobility and the flow of pedestrians around the remaining block, considering that access to the Esplanada do Castelo is predominantly by car.
The proposal to plant ornithophilous species aims to improve the residual spaces (underused as parking lots) around the remaining court, as these are areas that receive direct sunlight most of the day. These species adapt to full sun, provide shade, attract birds such as scissor hummingbirds (Eupetomena Macroura), promote thermal comfort and enhance local biodiversity.

Generative design around the court remaining after the dismantling of Morro do Castelo-RJ. Gradient floor with 1 x 1m pieces of white, light gray, dark gray and black granite. Composition developed with rhinoceros software+ pluging grasshoper.
The generative design (creation of shapes determined by algorithms) of the floor was created in order to reinforce the crossing points ("nodes", in Kevin Lynch's words) that still remain from the original layout and those that have arisen as a result of its overlapping, thus creating a unity in the buffer area around the remaining court. These magnetic points ("fields", by Stan Allen) are important places because they are points of attraction where pedestrians interact with the city by being able to orient themselves and make route decisions.

This dissertation is an exercise in strategy and planning aimed at interpreting the Historic Center of Rio de Janeiro as a constantly changing network of connections, through the elements that resist and persist despite the ongoing transformations of the landscape.
The book An Evolutionary Architecture (1995), which presents an overview of 30 years of John Frazer’s work, was a major source of inspiration during the development of a functional prototype for reading and activating natural processes. Frazer explores emerging technologies to investigate the fundamental generative processes of form in architecture, aided by the cybernetic principles disseminated by Gordon Pask, in order to achieve symbiotic behavior and metabolic balance with the natural environment. Physical modeling played an important role in his research, leading to the construction of interactive machine-readable models that are subjected to evolutionary processes in response to the user and the environment.
Meanwhile, the book Ruptura e Contiguidade: a Cidade na Incerteza (2005) by Sérgio Magalhães highlighted the importance of developing a narrative to organize the strategies and techniques of landscape design. In his book, Magalhães evaluates urban planning experiences in various cities, focusing especially on Rio de Janeiro. What stands out is his broad reflection on space and time in urbanism. He shows how the concept of time — which has changed since antiquity to the present, including Einstein’s theory of relativity — influences both human and urban relations.
I believe that the main contribution of this dissertation lies in the effort to interact, listen, and learn through dialogue with environmental impulses, supported by cybernetic principles, in an attempt to develop a landscape project that simultaneously engages with the different time scales involved in order to reach a utopia.
Nevertheless, the research still lacks the development of algorithms to organize the data gathered by the prototype on flocking bird behavior and to select which bird sounds should be reproduced in the environment. This tool, connected to the prototype, is essential for testing within the study area.
Even so, the research was successful, as I was able to establish dialogue with professionals from various fields such as biology, engineering, and the arts — all of whom were optimistic about this type of project-based approach. I hope that from this work, the integration of sustainability and urban planning with the art of cybernetics will become a constant in my professional life.
