The Shanghai Expo Culture Park fills the gap left by the incredibly large mass of empty concrete surfaces created for the Shanghai World Expo in 2010. Probably the most audacious urban renewal project currently under construction in Shanghai -- spanning over 85 hectares -- it forms a key component of the Huangpu riverfront revitalization on the Pudong side and part of the "Sponge City" blueprint to dramatically increase the amount of permeable surface area to help mitigate the risk of flooding and enhance the quality of the city's water supply. Anyway, it's a big new park, with lots of green space, and part of it is already open. The entire park will open 2024. The park also hosts the Shanghai Grand Opera House, the Shanghai International Equestrian Center and more attractions.
