Levín Castle, Medieval castle ruin in Levín, Czech Republic.

Levín Castle is a medieval fortress whose remains stand on a hilltop between Úštěk and Verneřice, with only fragments of the fortress walls visible today. The ruin sits about 13 kilometers northeast of Litoměřice and can be reached through the town of Levín.

No written record survives from the castle's existence; the first mention of Levín dates to 1352, and a 1538 charter refers only to a piece of forest for planting a vineyard "in the castle site below Levín". Archaeological finds place its origin in the second half of the 13th century and its end during the 14th century.

The hilltop later served as a cemetery, where a chapel or church of unknown dedication was built at the turn of the Renaissance and Baroque periods; its remains are what visitors often mistake for castle walls. The bell tower on the summit was built only after the castle ceased to exist.

The ruins are accessible from the town of Levín, which lies northeast of Litoměřice and serves as a good starting point for visits. The area features rolling hills and offers several walking and approach options to reach the site.

The summit holds no walls, but the southern slope keeps fragments of the rampart and the northeast a ground-floor remnant that may have been a chapel. Rescue research after damage in 2005 found late 14th-century architectural elements and traced two gates and the access path from the northeast.
