Friday Four - Docklands and Greenwich
84 Matilda is in the part of the Museum of London which is in Docklands. 5 Piquant is on the right hand side of an entrance to Greenwich Market. 52 Clair de Lune and 128 Cotee are at the Greenwich visitors centre next to the Cutty Sark (which is still undergoing conservation, so not much to see).
Cotee is the easternmost known Elephant on Parade, but a walk up the hill in Greenwich Park to the Royal Observatory and the Prime Meridian at zero degrees longitude and I think that all the elephants are in the West.
Total 244.
