• A 12.6 kg gold bar kept behind the old strongroom door, and visitors are allowed to reach in and touch it
• A banknote with your face, made at an interactive station that also mints a virtual coin for each visitor
• Closed Mondays and Tuesdays, open Wednesday to Sunday 10am to 6pm, with free entry

Set in the former São Julião church, the Bank of Portugal's museum traces money from the first Western coins to modern banknotes. Kids can touch a 12.6 kg gold bar behind an old vault door, virtually mint a coin and print a banknote with their own face, and look at banknote fibers under a microscope.

A stretch of King Dinis's medieval city wall is preserved inside.
