敷春堂西北的长岛上原有涵秋馆,占地面积1万平方米。 涵秋馆建于嘉庆年间,是绮春园春(敷春堂)、夏(清夏斋)、秋(涵秋馆)、冬(生冬室)四季景观之秋。涵秋馆坐北朝南,为七间双工字大殿,外檐悬嘉庆御笔“涵秋馆”匾。在双工字大殿的天井中设有叠石喷泉。
涵秋馆前后殿内均建有仙楼(二层阁楼),后殿东经套殿折而北还建有三间套殿。嘉庆皇帝对涵秋馆这组建筑很是喜欢,曾有诗句“遇润秋来早,新凉庭院涵。松梢涛韵漾,池上镜光含。旭皎辉高宇,明霞衬远岚。蝉音答丛樾,何馥送澄潭。”
在涵秋馆东山外侧山凹处,建有点景之露水神台,亦称仙人承露台。据说立仙人承露起源于秦汉时期,最初立于阿房宫前,后来汉武帝又将其立于建章宫内。传说汉武帝为了长生不老,幻想用
铜仙承露盘收集露水和着玉屑而服用,以求长生不老。
The three-Arch Bridge was originally built with stone and bricks. When the garden was destroyed, the bridge was also leveled to the ground. The present one was constructed in 1979, with stone piers, cement arches, and marble railings.
