Visitors to Lagos can also take time to discover some of the town's history by visiting the Church of Santo António, the slave market dating back to 1445, sections of the old city walls and several statues built to the famous figures from the past. One of the most noticeable is the one sculpture of Dom Sebastião standing in the main square. Few historic buildings remain in Lagos, apart from some ruins in the old section of town, because of an earthquake in 1755.
