Constructed between 1207 and 1209 by the Livonian Brothers of the Sword, this castle lies mainly in picturesque ruins after being severely damaged during the Great Northern War. Some sections have been restored and you can now walk along the front ramparts and ascend a tower at the rear where there are wonderful views over the forested Gauja Valley. See if you can spy Krimulda Manor and Turaida Castle poking through the trees.
In the warmer months you can also take part in archery and other knightly pursuits. At the centre of the complex, a summer stage has been erected.
