Bradlec, Medieval castle ruin in Újezdec, Czech Republic.

Bradlec is a castle ruin on a basalt hill at 542 metres above sea level, 500 metres northwest of Újezdec. Its core has an elongated trapezoidal plan with a square residential tower, a palace with a semicircular bastion, and a small remnant of the outer ward wall. Most walls are rubble stone, while the palace and bastion use sandstone blocks.

Bradlec Castle was founded in the late 13th or early 14th century. Its first documented owner, Havel Ryba of Bradlec, used it in 1316–1323 for a private war against Vok of Rotštejn. In 1356 Charles IV had to besiege it because it sheltered robber knights, and in 1421 Čeněk of Vartenberk captured it. By the early 16th century it was abandoned.

The name Bradlec comes from the sharp basalt hill the castle stands on. The core had an elongated trapezoidal plan, probably a block-type castle, with a square residential tower flanked by barrel-vaulted annexes and a palace with a semicircular bastion on the east side. Most walls are rubble stone, but the palace and bastion were built of sandstone blocks.

The ruin lies 500 m northwest of Újezdec and 7 km northeast of Jičín, on the blue-marked trail; the summit is at 542 m, so expect a climb of roughly 90 m from the village. The path crosses forest and open ground, and the rock is slippery after rain.

The castle name comes from the sharp basalt peak it stands on, and the local rock also yielded chalcedony, psilomelan, siderite, analcime, thomsonite and magnetite. The site has been protected as a cultural monument since 1964.
