The Former Marine Police Headquarters Compound, completed in 1884, is located in Tsim Sha Tsui, Kowloon, Hong Kong. From 1884 to 1996, the Compound served as the headquarters for the Marine Police, which moved to Sai Wan Ho in 1996 and became a branch in the Hong Kong Police Force.

The compound is a declared monument since 1994 as it is one of the four oldest surviving government buildings in Hong Kong. The Compound and the Old Kowloon Fire Station have been re-developed into a heritage hotel with food and beverage outlets and retail facilities in a project headed by architect Daniel Lin of A+T Design, opened in 2009. The site is now officially renamed as 1881 Heritage.

The compound was completed in 1884 and served as the headquarters of the Water Police (as they were originally known) until late 1996. The main building was originally constructed on the waterfront, and had a dedicated slip prior to the reclamation of land to create Salisbury Road. To the east, the headquarters faced a sandy beach.

During the Japanese Occupation (1941–1945), the compound was used as a base for the Japanese navy. At this time, an extensive network of tunnels were constructed beneath the lawn but after World War II, these tunnels were blocked and the lawn was returfed for the safety of public.

In the 1970s, the compound lost a large part of its gardens, when the slope to the east was levelled to make way for the construction of Kowloon Park Drive.

The station was colloquially referred to as T-Lands Police Station – probably a reference to Marine Police brevity code for a marine police station on "Land" at "Tsim Sha Tsui". This name is used in at least two novels set in Hong Kong: Soldier of Fortune by Ernest K. Gann, published in 1954; and Dragon Flame by the house author Nick Carter, published in 1966.

In 2002, the Hong Kong Government announced a competitive tender for an adaptive reuse concept for the former Marine Police Headquarters, which had been vacant since 1996; to entice tenders, the conditions included permission to create up to 7,213 m (77,640 sq ft) of floor space below the Main Building.

The Government announced on 23 May 2003 that Flying Snow Limited, a subsidiary of Cheung Kong Holdings, had won the 50-year land grant at a tendered price of HK$352.8 million, out of six competitive proposals. The approval allowed the developer to preserve and redevelop the historical building into a heritage tourism facility. Flying Snow has transformed the building into a heritage hotel with food and beverage outlets, and retail facilities. The project was the first private sector-led preservation project in Hong Kong; under the terms of the land grant, specific furnishings and features were required to be preserved and restored. The project opened as 1881 Heritage in 2009, and was criticized for removing most of the trees from what was once a grassy hill.

In 2010, the South China Morning Post reported the estimated floor space in the existing buildings had not been correctly surveyed and was 5,610 m (60,400 sq ft), instead of the 4,300 m (46,000 sq ft) originally submitted for the tender; in addition, the finished project added 7,413 m (79,790 sq ft), an extra 200 m (2,200 sq ft) above the tender, for which Cheung Kong paid an additional HK$94.5 million. Because the prevailing market rate was HK$1 million per square metre, the under-counted existing floor space and below-market rate paid for the extra construction collectively were estimated to have provided an effective HK$1.5 billion bonus to Cheung Kong Holdings.

The Signal Tower (Chinese: 大包米訊號塔; Jyutping: daai6 baau1 mai5 seon3 hou6 taap3), also known as the Time Ball Tower or Round House, was constructed to provide time signals to ships in the harbour. A ball was hoisted each morning and dropped precisely at 1 PM. Its use diminished in 1907 when the time ball apparatus was removed to Signal Hill, Kowloon.

The Old Kowloon Fire Station, also known as the Former Tsim Sha Tsui Fire Station, was originally completed in 1920; a charity shop selling handcrafts occupied the space starting in 1986 until the 2003–09 renovations.

The Fire Station Accommodation Block is immediately north of the Old Kowloon Fire station, and was completed in 1922.
