The London of Sebastian St. Cyr: Tattersall's

Located near Hyde Park Corner, Tattersall's was a popular fixture during the Regency period. Not only was it the foremost auctioneer of expensive horseflesh, but its subscription rooms were a fashionable gathering spot for sporting men--a place where gentlemen could meet and drink and lay their bets. (Hence the threat of "settling day at Tattersall's.")

Originally founded in the mid-eighteenth century by Richard Tattersall, a former groom to the Duke of Kingston, it contained stables, two subscription rooms, a counting house, covered galleries, a courtyard with its iconic temple-covered pump, and kennels. The kennels were necessary because in addition to horses and carriages, Tattersall's also sold hounds.

Later, in the Victorian era, the establishment was forced to move to Knightsbridge, and then relocated again to Newmarket. It also dropped the apostrophe from its name. But it still exists, and is still considered the leader in its field.

Because Tattersall's was such a fashionable lounging spot, Sebastian has been known to confront suspects in its famous courtyard. One such scene takes place in What Darkness Brings. But he'll no doubt be back again in the future....
