The Museo de los Cabildos occupies the former City Hall building on the Zócalo and holds one of Mexico City's finest colonial rooms: a viceroy's wooden chair collection, portraits of every Nueva España viceroy, and murals depicting the city in the 16th and 17th centuries. Entry is free and the visit takes 30 minutes, but getting inside requires negotiating past police at the security barriers - there's no museum signage, which keeps crowds light. The honest catch is operational: posted hours aren't always kept, staff at the door apply inconsistent judgment, and unannounced closures happen. When it opens and a guide is present, the experience exceeds what its size suggests.
The Salón de Cabildos, with its original furniture and floor-to-ceiling portraits of New Spain's viceroys, is genuinely worth the effort. The effort is real: there is no visible sign, police at the entrance control access, and unannounced closures are common, so confirm before you go
