Stádlec is known for its rare Stádlec Suspension Bridge over the Lužnice River. It connects Stádlec with the village of Dobřejice (part of Malšice). For its value, the bridge is protected as a national cultural monument.

Stádlec Castle was originally a fortress, first documented in 1535. In the 17th century, it was rebuilt into a castle. The castle chapel was added in 1712–1714. In the mid-18th century, the castle was rebuilt in the Baroque style and extended. Today it is privately owned and inaccessible.
