Just north of the ridge summit of Cefn Bryn, there is a neolithic burial ground, known as 'Arthur's Stone' (Maen Ceti). Its name comes from a legend that the ancient British King Arthur threw a large stone from Llanelli which landed on this spot.
It is believed that during the Bronze Age Cefn Bryn was used extensively for ceremonies and rituals. Beneath the bracken on the hill over sixty cairns have been discovered. Most of these are likely to be no more than collections of stones cleared by local farmers; but just north-west of Arthur's Stone three prominent cairns have been excavated that prove their ancient role - the largest being Great Cairn, a circular heap of stones above a central grave.

Its name Červená Lhota meaning 'red lhota' can be explained by the colour of the château"s bright-red roof tiles. There is also a park, where the Chapel of the Holy Trinity is located.
The existence of an original fortress on the site of today"s château is assumed from sometime around the middle of the 14th century. It was built on a rocky granite outcrop, which, after the damming of a stream and the filling up of a fishpond, became an island. The first written source is an entry into the land records from 1465, mentioning the division of the property of deceased Ctibor of Zásmuk between his two sons Petr and Václav.
