Schloss Friedrichsthal

德国的 Schloss Friedrichsthal 是一座巴洛克建筑，三翼围合出安静的庭院。它建于1708年至1711年间，最初作为萨克森-哥达-阿尔滕堡公爵腓特烈二世的夏季住所。宫廷建筑师 Wolf Christoph Zorn von Plobsheim 负责了这座宫殿的设计，整体布局带有凡尔赛宫式建筑的秩序感。

宫殿东侧曾经延伸着巴洛克花园，园内设有雕像、水景和洞窟。花园后来被其他建筑取代，对面的橘园仍以柑橘植物和几何花坛延续部分旧日景观。19世纪，Johann 和 Friedrich Weidner 为 Schloss Friedrichsthal 增建了新的侧翼。公爵夫人 Karoline Amalie 和萨克森-科堡-哥达的 Leopold 亲王都曾把这里作为夏季居所。

如今，宫殿空间由一所州立技术学校使用，原有功能已经发生改变。修复后的建造时期灰泥天花板，仍然保留着这座建筑的历史细节。 facades and rich interiors? Chinese: 外立面和内部装饰. Need sentence concrete. Add final. But current ~220 Chinese chars maybe enough.
