Château or Donjon de Bours was most likely built in the 12th century by Hugues de Bours. Originally it would have had a bailey defended by a crenellated wall guarding several outbuildings. Both the bailey and the castle would have been moated. At present all traces of the bailey are gone.
Bours Castle is a keep built out of sandstone and has a rectangular plan with six corbelled turrets. It has walls of 70 cm thick and 2 floors. It is generally assumed that during the mid-13th century the keep would have been higher.
During the first half of the 15th century the castle was owned by Maillotins de Bours who restored and enlarged the castle but probably did not change the keep.
In 1543 Bours Castle was burned down.
At the beginning of the 20th century there was talk of demolishing the keep but luckily that did not happen. During the second half of the 20th century the keep was restored several times and used as a town hall.References:
Heidelberg Castle is a famous ruin and one of the the most important Renaissance structures north of the Alps. The rich and eventful history of Heidelberg Palace began when the counts palatine of the Rhine, – later prince electors – established their residence at Heidelberg. The earliest castle structure was built before 1214 and later expanded into two castles circa 1294; however, in 1537, a lightning-bolt destroyed the upper castle. Until the Thirty Years’ War, Heidelberg Palace boasted one of the most notable ensembles of buildings in the Holy Roman Empire. The present structures had been expanded by 1650, before damage by later wars and fires. In 1764, another lightning-bolt caused a fire which destroyed some rebuilt sections.
The 19th century brought a new wave of admiration: a sight both terrible and beautiful, the ruins epitomised the spirit of the Romantic movement. Heidelberg Palace was elevated to a national monument. The imposing edifice and its famous garden, the Hortus Palatinus, became shrouded in myth. The garden, the last work commissioned by the prince electors, was never completed. Some remaining landscaped terraces and other vestiges hint at the awe-inspiring scale of this ambitious project. In the 17th century, it was celebrated as the “eighth wonder of the world”. While time has taken its toll, Heidelberg Palace’s fame lives on to this day.
Heidelberg Castle is located 80 metres up the northern part of the Königstuhl hillside, and thereby dominates the view of the old downtown. Set against the deep green forests on the north flank of Königstuhl hill, the red sandstone ruins tower majestically over the Neckar valley.
