补充资料:安梁堡梁氏大宅
安梁堡梁氏大宅位于广东省高州市曹江镇安梁堡村。距离高州市中心约13公里,是典型的中西艺术交融,富有时代代表性的民国民居建筑。大宅是当地著名乡坤梁普埙、梁普篪兄弟的旧居,建成于1947年,占地面积达一万一千多平方米,建筑面积达四千多平方米。主体建筑分为东、西两宅,分别由前楼、后楼和侧楼组成,前楼一层,后楼三层,侧楼二层,前后楼之间有天井,并通过多条走廊相互贯通,连为一体。在功能分布上,后楼是主楼,是梁府家庭成员的生活起居住宅,前楼是雇工住宅和生活服务区,侧偻用于储存食物和物品。大宅还配套有花园、水井、池塘、厕所、猪舍、牛栏、码头等设施。大宅整体是中国传统的楼阁式,同时配合了西式的走廊和装饰。大宅的排水系统也别具一格,落到大宅的雨水通过管道进入天井中的大水池,水池水满后才往外排泄,因此,水池常年储满水,可备发生火灾时使用。大宅主体建筑对外的墙体上,每间隔一定的距离,就开有射击孔和瞭望窗,和大宅四周的围墙、护卫角楼组成了坚固的防御系统,从而使大宅成为一座集防卫、住宅、贮藏于一体等综合使用功能的建筑。
