We are in Star Yard WC2 where I found this ornate but modern bollard with it's circular base and tapering vertically ridged body. The top of the bollard flares outwards and then turns into an almost bell like shape finished off with a nipple tip/top.
Star Yard just happens to be home of a rather interesting tailor called Ede and Ravenscroft who were founded in 1689. The bollard(s) simply ensure nobody parks on the stone/cobbled area in front of the shop.
