Lilleborg, 3 August 1821 The castle was probably built in the middle of the 12th century as a royal fortress. It appears to have replaced the much larger fortress of
Gamleborg which was only away. The move could be explained by the fact that in 1149, three-fourths of Bornholm had been surrendered to
Eskil,
archbishop of Lund. As a result, King
Sweyn III wanted to establish his own seat of power on the remaining fourth of the island. While it could not be compared to the archbishop's
Hammershus, Lilleborg was nevertheless a fine stronghold and appears to have been easier to defend than the much larger Gamleborg. There is evidence suggesting the fortress burnt down in 1259 when
Prince Jaromar of Rügen stormed and destroyed the "king's stronghold" on Bornholm. However, coins minted after that date have been found, indicating it was inhabited after its storming. ==Architecture==
