Brockwell Park is a 50 hectare park located between Brixton, Herne Hill and Tulse Hill, bordered by Brixton Water Lane, Norwood Road, Tulse Hill (Road), and Dulwich Road in South London.
The park commands views of the skyline of the city and Central London, and hosts almost 4 million annual visits. At the top of the hill within the park stands Brockwell Hall.
Brockwell Park is a Site of Importance for Nature Conservation (SINC) of Borough Importance, with mature trees including ancient oaks, substantial lawn areas set to meadow, and a series of lakes. As well as adding to the landscape value, these support a variety of birds, and bats.
The Park is listed for its heritage value on The National Heritage List for England, Parks & Gardens, Grade II. Noted for its nineteenth century layout as a gracious public park, the clocktower, water garden, JJ Sexby designed walled garden and other monuments, the park provides a pleasant exploration with links to its eighteenth century agricultural past in the hedge lines, and mature oak trees.
The Brockwell Lido, a Grade II listed art deco building near the top of the park, is an open-air swimming pool popular with swimmers and bathers. Its attached café/restaurant is also popular. Other amenities in Brockwell Park include tennis courts, a bowling green, a BMX track and a miniature railway.

Listed buildings and structures are officially designated as being of special architectural, historical or cultural significance. There are over half a million listed structures in the United Kingdom, covered by around 375,000 listings.
Listed status is more commonly associated with buildings or groups of buildings, however it can cover many other structures, including bridges, headstones, steps, ponds, monuments, walls, phone boxes, wrecks, parks, and heritage sites, and in more recent times a road crossing (Abbey Road) and graffiti art (Banksy 'Spy-booth') have been included.

In England and Wales there are three main listing designations;
Grade I (2.5%) - exceptional interest, sometimes considered to be internationally important.
Grade II* (5.5%) - particularly important buildings of more than special interest.
Grade II (92%) - nationally important and of special interest.

There are also locally listed structures (at the discretion of local authorities) using A, B and C designations.

In Scotland three classifications are also used but the criteria are different. There are around 47,500 Listed buildings.
Category A (8%)- generally equivalent to Grade I and II* in England and Wales
Category B (51%)- this appears generally to cover the ground of Grade II, recognising national importance.
Category C (41%)- buildings of local importance, probably with some overlap with English Grade II.

In Northern Ireland the criteria are similar to Scotland, but the classifications are:
Grade A (2.3%)
Grade B+ (4.7%)
Grade B (93%)
