Museum Speelklok is a museum of self-playing musical instruments housed in the Buurkerk on Steenweg, the oldest parish church in Utrecht's city centre. The collection grew out of a private assembly of automatic instruments and opened here in 1984. Roughly a thousand objects are in the collection, with a few hundred on display, and many still work, because the museum runs its own restoration workshop. What you find inside runs from tiny singing-bird boxes and musical snuffboxes through carillon drums, orchestrions, pianolas and dance organs to enormous Dutch street organs. The visit is built around a guided demonstration, the main event rather than an optional extra. A guide walks a group through the medieval nave switching instruments on: a Swiss music box the size of a book, an automaton that writes, a violin-playing machine, a pianola thumping out ragtime, and finally a Dutch street organ at full volume with bass drum and cymbal, which is genuinely physical at close range. Between tours you explore freely, with side galleries explaining how pinned barrels, punched paper rolls and bellows encode music, plus a hands-on section where children pump, crank and trigger things.
