Faro Municipal Museum is the second oldest museum in the Algarve, opening in 1894 on the 500th anniversary of Prince Henry the Navigator's birth. Housed in the beautiful 16th-century Nossa Senhora da Assunção convent, it contains a remarkable collection of Roman artifacts, religious art, and paintings. The main treasure is the Oceanus Mosaic from the 2nd-3rd century, discovered near the current train station and exceptionally well preserved. The peaceful convent cloister provides a lovely escape from the city.
