Even today, the former Reichsparteitagsgelände (Nazi Party Rally Grounds) in the south of the city is still home to gigantic ruins representing the Nazi regime’s deluded notion of grandeur. The 11 km² complex was where the Nazi Party orchestrated its propaganda campaign. The documentation centre is located in the north wing of the Kongresshalle, which was designed by the Nazis to hold 50 000 people and was never completed. The permanent “Faszination und Gewalt” (“Fascination and Terror”) exhibition housed in the 1300 m² venue, chronicles the causes, relationships and consequences of the Nazi dictatorship.

A must-see while in Porto is the São Bento Railway Station. More than just a train station, this place is another architectural jewel, among the many others this city boasts. Built by the Portuguese architect José Marques da Silva in 1900, the São Bento Railway Station opened to the public sixteen years later. Its construction took place on the site that once housed a Benedictine monastery, hence the name São Bento. The architecture has a French Renaissance influence, and even though its facade is already quite impressive, its interior is what leaves visitors truly awestruck. The main hall is beautifully decorated–from the ground to the ceiling — with more than 20,000 "azulejos" (Portuguese tiles), which recount important events of the history of Portugal.

The little fort dating from 1522 has been restored and is worth a visit, though the most remarkable aspect is still its view of Marmaris. The museum hosts various artifacts from antiquity and several Medieval cannons.
