Welcome to Knightsbridge a very pleasant rather wealthy part of the capital where I came across these ornate looking bollards that happen to be similar to to those we find in the Royal Borough of Kensington and Chelsea but on closer inspection they are very different. Please compare by clicking on the link 'The Waltons and some Bollart' you should notice that the egg cup/acorn top is similar along with the ornate middle but the body on the bollard (above/below) is ribbed/ridged with many more rings/ridges at the base.
Note this part of London is actually still in Westminster and not the Royal Borough of Kensington and Chelsea. Its also home to the 'Libyan Embassy' here in London.
