The tall granite column in Lemon Street Gardens commemorates Richard Lander, a Truro-born explorer who solved the mystery of where the Niger River flows — something that had puzzled European geographers for centuries. He traced the river to its delta in 1830 and won the first ever Royal Geographical Society Gold Medal.
The monument is a quiet and slightly obscure corner of Truro, but the story behind it is remarkable. Lander grew up in the city, the son of a publican, and is one of Cornwall's more forgotten heroes. The column gives fine views over the gardens and toward the cathedral.
