坪洲有一座早於1930年代初開設的牛皮廠，於2010年被古蹟辦事處列為三級歷史古蹟，被一位坪洲島民改造為活化藝術空間，稱為秘密花園。
入口位於永安街，一抬頭便能看見有一對牛角的牛皮廠的招牌，角落寫著秘密花園。走入小巷，牆上有藝術塗鴉，頭上天花板以紙杯創作圓形藝術裝置，亦有很多廢物改造藝術品，十分有創意。
A leather factory in Peng Chau that was opened in the early 1930s, listed as a Grade III historical building, was revitalised into an art space called “Secret Garden” by a Peng Chau islander.
The entrance is located on Wing On Street. When you look up, you can see the sign of the leather factory with a pair of horns, and the corner says Secret Garden. Walking into the alley, there are artistic graffiti on the walls, round art installations made of paper cups on the ceiling, and also many up-cycle artworks made with discarded items. Very creative!
