This is linked to the John Olson story - he was the publican of this Tavern for many years.

Initial discussions of its location placed it much further west, based on an address given as "292, Queen's Road West". Today, that address is for a building on the corner of Centre Street and Queen's Road West in Sai Ying Pun.

But in fact the tavern was back in Sheung Wan. We can confirm that from the mentions of the Tavern in the newspaper reports of Annual Licensing sessions:

In last month's visit to the Braemar Hill AOP, we also took the chance to take a look in the tunnel beneath it.

The tunnel is more complex than the usual 'dig a hole in the hillside'. First they had to make this hole in the AOP's floor:

Though it was described as a stone bridge, it was actually a pier, extending out into the shallow waters of Kowloon Bay. It was first built in the 1870s by the Chinese government, enabling easier access to Kowloon City by boat.

The pier changed shape several times, as reclamation ate it up from the landward end, and different extensions were added to it at the seaward end.

It disappeared from sight completely in 1942, during reclamation for the expansion of Kai-Tak airport by the Japanese.

There were dockyards here from the 1850s:

Built by John Lamont, in the 1850s, the first dock [to the west] was known as the Lamont Dock and proved highly successful. In the early 1860's, Lamont added another dock to his enterprise, the Hope Dock [to the east], but before the latter was finished, both docks were bought, in 1865, by the large and very successful firm, the Hong Kong and Whampoa Dock Co. of Hung Hom.
