“岭南第一大围”和“粤北第一民宅”经过半年多的维修整治，被誉为“岭南第一大围”、“粤北第一民宅”的全国重点文物保护单位——广东韶关始兴满堂客家大围第一期维修工程日前已经结束。大围正以焕然一新、恢宏雄伟的气势喜迎四方来客。 满堂客家大围坐落于中国近代史上著名的爱国将领、抗日战争时期曾任国民党第四战区总司令的张发奎将军的故乡——广东韶关始兴县隘子镇，离韶关市区东南方约八十公里。挂于围楼门上的横匾“满堂客家大围”为一九九一年秋、时任全国政协副主席的客家人精英叶选平所书。 据《始兴文物志》记载，满堂客家大围奠基于中国清代道光十六(公元一八三六)年，为当时当地首富官定祥(时任清代道光候缺正五品衔)所建，历时二十八年才竣工。 跟粤东闽西一带的圆形客家围楼不同，满堂围是方形大围，属清代砖石结构的四合院式围楼。其外观为一整体，围内则由三个建筑群组成：中部为“中心围”，南部为“上新屋”，北部为“下新屋”。总体平面呈长方形，占地面积约一万三千平方米，有十二个院、九个厅、六个天井。共建有平房、楼房、炮楼等居室七百七十七间，是广东省规模最大的砖瓦结构围楼，有“岭南第一大围”之誉。 由于大围已历经一百四十多年的风雨侵蚀，许多地方都出现了不同程度的安全隐患。为维修和保护好这一珍贵历史文化遗产，始兴县从半年多前就开始聘请有关专家、工程技术人员对满堂围进行了全面的资料搜集、整理和测绘、维修。目前已完成的第一期工程主要是对中心围进行维修，重修围内崩塌的瓦梁、门窗、墙壁等。维修后的满堂客家大围保持了原有雄浑朴实的气势和精致高雅的韵味。 如今，居住在满堂客家大围仍有四十多户人家，全都是官姓家族的后裔。姓氏没有变，大围的外观也没有变，可村民们的思想观念、生活方式却发生了翻天覆地的变化。在市场经济的浪潮中，大围内开起了小商店、小工场，开进了汽车、摩托车，开通了电话、电视，还有那古老大屋天花板上传统的图案花色与厅堂四周颇具现代气息的装修陈设互相辉映，令这边远山村的大围屋越来越有生气，越来越有希望。 大围外面那精彩的世界对围屋内的村民，尤其是年轻一代的吸引力越来越大。他们陆续跨出那厚实的铁木大门，到围外去闯荡世界，创造人生。然后，给古老的大围带回一套套更新的观念，带回一串串崭新的词语，带回一个个致富的信息，也带回一笔笔可观的财富。
