There is no shortage of beautiful monuments and attractions to explore. For starters, the Mercado do Bolhão is a traditional market selling fruit, vegetables, fish and meat in the friendly atmosphere that Porto is known for. Travellers can follow that with a trip to the Palácio da Bolsa (the old stock exchange), known for its Arab Room, which is decorated in the exotic Moorish revival style. The Praça de Lisboa plaza attracts tourists with the Clérigos Church and its splendid tower, both fine examples of classic Baroque architecture and motifs. And last but not least, the Sé Cathedral, one of the first Romanesque monuments built in Portugal, cannot be missed.
