Jerónimos Monastery is one of the most well-known sites in the Portuguese capital city of Lisbon. It is situated across the street from Empire Square (Praça do Império), just north of the Tagus River. Dating to the late 15th century, the monastery was substantially altered in the late 1800's to take on its current Late Gothic architectural style. Seen here in this excellent drone video by sphereview, the monastery complex has been designated as a UNESCO World Heritage site since 1983.
