These courtyards for the Eunuch and Concubine quarters could now be thought of as "mini-museums", filled as they are with Ming art (paintings, stonework, bronzes, etc.) and furniture. This gives a visitor a chance to browse casually and slowly, without the press of the large number of visitors in the main parts of the Forbidden City, and catch one's breath.
Though there aren't the super-scale carvings, columns, etc., to be found outside of this little area in the northern part of the Forbidden City, there is all of the elegance on a more personal-sized scale.
It costs a few Yuan to visit these areas, but I would consider it well worth it to see the quieter side of the Forbidden City.
