Seeking a Thamesmead Orchard

An orchard for the enjoyment of local people was reportedly planted around twenty years ago on the edge of Crossness Park. However, after two walks in the area, all I could locate was an apple tree beside the Ridgeway Path. Does anyone know the Orchard?

My tree was in abundant fruit with a carpet of apples already on the ground for insects and birds. It tasted a bit like a Granny Smith; tart and acidic with a subtle sweet flavour and crisp, firm white flesh. Perhaps it’s a wilding grown up from a seed from a thrown away core, but not the kind of focused planting I was looking for.
