The Mews section is now closed and many of the dealers from that part of the building now trade from the sister company Alfies Antique Market located in Marylebone. The Mews section of Grays was built circa 1900 and was also taken over by Bolding in 1931. The basement of the Mews had been under six feet of water for many years, and on closer inspection it was found that a spring arose from one end of the building. Now renovated, the shop claims that the water flowing through a conduit in its basement is the
River Tyburn, which rises in Hampstead and flows underground towards the River Thames. The
Londonist website describes this suggestion as "fanciful", as the modern Tyburn is contained in a conduit. ==See also==
