Tvrz Nebovidy, Medieval fortified house in Nebovidy, Czech Republic.

Tvrz Nebovidy is a four-winged, two-storey stone fortress with a closed square courtyard, standing on a small rise called "Na Valech" above the Nebovidský potok valley. Its square layout comes from a Renaissance rebuilding; the ground floor keeps Gothic elements such as walled-up windows and lunette vaults with ridges, and the outer walls show fragments of sgraffito bossage and Baroque plaster layers.

Nebovidy is first mentioned in 1268 with Kunata of Nebovidy, though August Sedláček cites 1235. In the 14th century the village was split in two, each part with its own fortress; the lower one passed in 1473 to Jindřich of Nebovidy, who sold all of Nebovidy to Jan Plzák of Nebřeziny. In the second half of the 16th century the Hanykéř of Semín family, Kutná Hora burghers enriched by the silver trade, rebuilt it in Renaissance style.

The lower fortress is owned by the municipality of Nebovidy, and the association Nebovidská tvrz works with the village on its rescue and use. The association organises cultural performances, film screenings, guided tours and social events in the grounds during the year. The village flag and coat of arms adopted in 2005 take the oblique silver bar in a red field from the arms of the lords of Nebovidy.

The fortress stands next to the municipal office in the centre of Nebovidy, on a rise called "Na Valech" above the Nebovidský potok valley. A bus stop served by regular connections from Kolín is right by the building; the nearest train stops are Hluboký Důl and Červené Pečky. The interior is open during cultural and social events organised by the Nebovidská tvrz association.

The house is one of two noble residences that once stood in the village, though its neighboring fortress Okrouhlá disappeared centuries ago. Being the sole surviving example of its kind in the area makes it a rare window into the medieval settlement pattern of the region.
