The name is an ambitious misnomer as there are not many genuine Yuán-dynasty relics here, but this slender strip of parkland, running alongside the Little Moon River (Xiǎoyuè Hé), commemorates a strip of the long-vanished Mongol city wall that it is built upon. At 9km in length, this is Běijīng’s longest parkland and a relaxing place for a stroll.
