Uuskasutuskeskus

Why it matters: run by a nonprofit since 2004, Uuskasutuskeskus (Reuse Centre) keeps roughly 250,000 items a month out of landfills and channels support to more than 50 charity partners across Estonia. The Tatari 64 shop is the chain’s biggest and most central – a warren of secondhand dishes, books, clothing and furniture at prices that make it Tallinn’s favorite eco-souvenir stop. Dig for old Soviet-era glassware or a stack of quirky Estonian paperbacks, and bring cash for the smaller odds and ends. Tram 3 or 4 to the Vineeri stop drops you right outside.
