蚵灰窯曾經是安平地區很重要的建材製造場所，也是目前台灣僅存唯一的蚵灰窯，從17世紀開始蚵灰便是以海為生的安平人必備的造船材料之一，後來延伸加入糖水、糯米汁成為蓋房的磚瓦黏合使用，現今雖然已不再使用這些古法建材，但仍舊保留了安平燒製蚵殼成為蚵灰的重要遺址，走進蚵灰窯會看見被愛玉子藤蔓覆蓋住的紅磚牆面，內部就是一座相當大的窯坑，內部直徑約4公尺，高度約為2公尺，窯體牆面最薄的地方還有1公尺厚，是難得一見的燒窯建築。
文化館區域內詳細敘述著蚵的成長過程及生態，蚵灰的製作過程，蚵灰的應用，讓遊客可以很清楚的認識這古早的技藝，雖然現在蚵灰被新的工業建材取代，已經走進歷史不再使用，但幸好有蚵灰窯文化館傳承，讓更多人認識17世紀安平的產業及建築方法。
