福建土楼

    ①福建土楼是东方文明的一颗明珠,它被誉为“东方古城堡”、“世界建筑奇葩”,“世界上独一无二的、神话般的山区建筑模式”。

    ②风格奇异的土楼民宅散布在闽西的永定、武平、上杭及闽西南的南靖、平和、华安、漳浦等地。其造型、装饰和建造工艺世所罕见,土楼,俗称“生土楼”。因其大多数为福建客家人所建,故又称“客家土楼”。它是以生土作为主要建筑材料,掺上细沙、石灰、糯米饭、红糖、竹片、木条等,经过反复揉、舂、压建造而成。楼顶覆以火烧瓦盖,经久不损。土楼高可达四五层,供三代或四代人同楼聚居。

    ③福建土楼大多具备完善的防御功能。其外墙厚一至二米,一二层不开窗,仅有坚固大门一关,土楼便成坚不可摧的堡垒。为防火攻,门上设有漏水漏沙装置,紧急时楼内居民还可从地下暗道逃出。如今,土楼早已不再是堡垒,但那些完备而精致的防御设施,仍让人们拍案惊奇。

    ④厚重的福建土楼,承载着厚重的传统文化。发人深省的楹联匾额,与楼共存的私塾学堂,教化育人的壁画彩绘,无不激荡着历朝历代土楼人家“修身齐家”的理想和“止于至善”的追求。振成楼有副楹联备受称道:振作哪有闲时,少时壮时老年时,时时须努力;成名原非易事,家事国事天下事,事事要关心。

    ⑤2008年7月福建土楼被列为世界文化遗产。
