The National Museum of Musical Instruments sits right next to Santa Croce, making it easy to find for anyone exploring the area. This museum holds an impressive collection of about 3,000 instruments from different eras and places around the world.
Although the museum has thousands of pieces, only about a third are on display at any time. Visitors can expect to see a wide variety of musical instruments, from grand pianos and ancient harps to unique stringed and wind instruments. The displays highlight the craftsmanship and history behind each piece, showing how music and culture have evolved over the centuries.
