Strategy / Regional analysis:
Trafaria village. Military heritage photographs: Alpena Fort, building and view respectively
Trafaria village is mostly found inset in a region with null elevation, creating thus not only a very intricate connection to the river Tagus, but also a very strong, visual one with a terrain of higher (and natural) ground. It had come to be used, over the years, as a particularly important focus of military construction so nowadays these constructions have become obsolete, and were promptly abandoned. The first construction to be acknowledged refers to the 17th century: a large wall facing Tagus. The remaining three, however, are more recent, dating back to the 20th century and are found in the highest point of Trafaria.
