• Book tickets ahead, since the official site warns they often sell out and can't be bought on the day
• Church on its own hours: 10:30am to 5pm Tuesday to Saturday, and only 2pm to 5pm on Sundays and religious holidays
• Half-price family ticket for at least one adult with one child, sold only at the kiosk in front of the monastery

Built from the early 1500s in pale lioz limestone, Jerónimos is the showpiece of Portugal's Manueline style, with knotted ropes, armillary spheres and sea motifs carved into the stone. Look closely and the stone itself is full of fossils.

The two-story cloister is the main visit, with arches kids can walk around on both levels. The church holds the tombs of explorer Vasco da Gama and poet Luís de Camões.
