By the excavations in 1969-1976 the archaeologists found two roman one-nave basilicas built in different times. They're called basilicae geminatae or “the twin churches” and their purpose is not clear. One idea is that the basilicae geminatae are a conjunction of the congregational churches that serve for the public worship mass and memorial ones intended for the cult of relics.

Another great lookout is Miradouro da Senhora do Monte, located in a churchyard. It is recommended to visit this lookout early in the morning or late at night when this magic city lights up right beneath your feet.

The Monument to King José I can be found right in the middle of Praça do Comércio — Lisbon's grandest square. The square, still often referred to as Terreiro do Paço by the locals, is the perfect starting point for your exploration of the city. The square is hugged by historic buildings complete with countless columns. The statue of King José I faces the Tagus River — a gateway to the New World, now a busy transportation hub with a ferry terminal and connecting tram lines.

The sprawling Cultural Plaza in Chinatown is a shopping square surrounding a courtyard that hosts an incense-enveloped shrine and the Moongate stage for holiday performances. Near the canal, you will meet local community members playing cards and mah-jong.
