One of the buildings often found next to a Roman forum is the basilica. It served as a place where people could meet. Basilicas had no statues of Roman gods and had beautiful light that came in through windows near the roof, so they were a favorite gathering place for early Christians.
The plan of the basilica was later adopted for the construction of important churches. Lisbon has an elegant basilica at Estrela, built in 1790 by Queen Maria I.
Few people seem to know that one can climb the stairs to the roof of the Estrela basilica and enjoy in peaceful silence breathtaking views of the city. It is a perfect place to meet Lisbon.
