North bank: the citadel and its ramparts
On the left bank of the Perfume River, the citadel built from 1805 forms a square about 10 km around, surrounded by moats. Inside is the Imperial City, but also a peaceful residential quarter of lakes, gardens and traditional garden houses. The fighting of 1968 destroyed much of the palaces, including the Forbidden Purple City, and restoration is ongoing. Allow half a day for the imperial enclosure, starting at opening time to avoid the heat, which is intense from May to August.
