Although often neglected in favor of more glamorous neighborhoods, the northern Shanghai districts of Putuo, Hongkou, and Zhabei still offer some interesting sights. Hongkou District is relatively undeveloped and unchanged, and buildings from the past are visible behind cheap clothing stores. Shanghai’s old Jewish Quarter is here, too. An area with an interesting history, Hongkou has the most sights worth seeing, as well as the lush green sweep of Lu Xun Park. The old buildings and warehouses around Suzhou Creek, which feeds into the Huangpu, are slowly being turned into a hip and happening arty area, particularly the M50 development. Also in Putuo District is another one of Shanghai's main temples, the Jade Buddha Temple.
