嗯，我去上海的时候听过。石库门出现于十九世纪中。当时大批难民因为打仗逃难到上海租界里，必须很多人挤在一所小房子里。久而久之，就形成了石库门这种两层楼的石质房屋。家门里面有一个很小的花园，叫天井。石库门中间细长的街道叫弄堂。以前，北京和上海的大多数居民都住在这些传统民居里。

Yes, I heard about it when I was in Shanghai. Shikumen came into existence in the mid-19th century. There was an influx of war refugees fleeing to the concessions in Shanghai. They had to cram into small houses. Over time, these evolved into a type of two-story house made from stone known as shikumen. There is a tiny garden inside the house called a tianjing. The long narrow lanes between shikumen houses are known as longtang. Most of the people in Beijing and Shanghai used to live in these traditional residences.
