Part of the National Roman Museum complex but completely overlooked by tourists in favor of capitoline museums. Houses one of the most important Roman sculpture collections outside Vatican Museums, including the Ludovisi Throne and Suicide of the Gaul - different masterpieces from what youll see at capitoline.

€15 entry covers all four National Roman Museum sites valid for 3 days. Open Tuesday-Sunday 9am-7:45pm. The courtyard with ancient sculptures is particularly stunning in afternoon light.

Located 5 minutes from Piazza Navona but feels like a secret. You can study pieces without fighting crowds or tour groups. Audio guide worth the extra €5 for historical context.
