With kids, give Calouste Gulbenkian Museum a miss.
The connoisseur's pick: a small, faultlessly chosen collection spanning Egyptian, Islamic, Asian and European art, capped by a dazzling room of Lalique jewellery, all in a serene garden. The honest catch: it's a metro ride north of the tourist core and 'just a museum', so it loses people chasing tiled-alley Lisbon. For art lovers it's the city's best museum.
Built around Calouste Gulbenkian's bequest; collection spans Ancient Egypt to a celebrated René Lalique Art Nouveau jewellery room, set in landscaped gardens. · gulbenkian.pt
The main Founder's Collection is closed for renovation until 2026; the gardens, CAM modern-art centre and concert hall remain open. · timeout.com
