There are tantalising glimpses of the remains of the Ming Dynasty city walls around the modern centre of Beijing. Some parts have been adapted and built up against, whilst some like this section are backdrops to tiny pocket parks, which provide much needed green space in a frenetic city. Often you have to take a moment to work out what you are looking at, as not all sections have interpretation panels (though many do, like this one). The sections provide intimate glimpses into the long history of settlement and the ever-present role of history and a deeply valued cultural story. They are used heavily as spaces for rest for workers from nearby offices and recreation space for flat dwellers in the vicinity who have little green space access otherwise.
