The ruins of Pravda Castle can be found at the top of a marlite hill, 284 metres above sea level. You can reach it after a 45 min. walk from the village of Pnětluky, or from the railway station in Domoušice. Pravda Castle was founded in the first half of the 14th century and it is connected with name of Albert of Kolowrat. The last owners left the castle sometime before the mid 16th century. The castle offers beautiful views over the plateaux of Rovina, Výrov and parts of the České středohoří (the Central Bohemian Uplands). The Rovina plateau is known for its Stone Lines that are one of our archeological mysteries. Nobody knows how and why they originated and disputes over theses issues have been held for many years. The Stone Lines are formed by 14 lines of quartzite stones, leading parallel in the distance of 20 to 30 cm apart; the lines are about 400 metres long.
