One of Helsinki’s newest and hottest flea market spots, Kaivarin Kanuuna is a self-service flea market, situated on the Kaivopuisto waterfront, within walking distance of Kaivopuisto Park. Open all year round, except on Mondays, Kaivarin Kanuuna is not a classic flea market, but it offers a similar experience. It is actually a large second-hand shop where you can find a bit more upscale second-hand items.
