This stately yet muscular building (1767) once served as a prison and now houses a photography museum. You actually walk through the thick iron gates and into the cells to see the work, which lends the intriguing exhibits even more gravitas. On the 3rd floor is a collection of cameras spanning every decade; particularly fascinating are the espionage ones, discreetly hidden in everything from Pepsi cans to Marlboro packets.
Immediately south of the museum are the narrow, atmospheric lanes that were once part of Porto’s judiaria (Jewish quarter).
