Haapsalu Resort Hall is one of the town's clearest reminders of its old life as a Baltic spa resort. The wooden hall and bandstand stand by the water, tied to the promenades, mud baths, and summer visitors that made Haapsalu fashionable with Russian aristocrats and later holidaymakers.
It is most appealing as part of a slow seaside walk rather than as a building to inspect in isolation. Come in soft evening light if you can; the resort architecture, water, and quiet promenade explain Haapsalu better than any single museum panel.
