Taverna ducale, Medieval civil building museum in Popoli, Italy.

Taverna Ducale is a 14th-century palazzetto in Popoli Terme, once belonging to the Cantelmo family, now a museum. Its facade carries a plaque recalling its origin as a casa-bottega for collecting tithes. The permanent collection of stone materials includes two headless Roman statues, a 1st-century pagan altar, a column with an Ionic capital, a limestone stele of the 1st–2nd century AD, and two 16th-century reliefs showing the Almighty and the Announcing Angel.

The building was erected in the second half of the 14th century as a "casa-bottega" for the Cantelmo family, to collect tithes on the produce of their estates, as a plaque on the facade recalls. It later became a tavern for buyers and wayfarers, with upper-floor rooms used as an inn. In 1875 Francesco Forniti bought it and used it as a stable before it fell into disuse and was acquired by the Ministry of Public Education.
