century, the park was landscaped, possibly by André Le Nôtre who is known at least to have designed plans for it. The public were first allowed into the park during the 18th century. Samuel Johnson visited the park in 1763 and commented "Is it not fine?". The famous hill upon which the observatory stands was used on public holidays for mass 'tumbling'. In the 1830s a railway was nearly driven through the middle of the lower park on a viaduct but the scheme was defeated by intense local opposition. However, the London and Greenwich Railway was later extended beneath the ground via a cut-and-cover tunnel link between Greenwich and Maze Hill which opened in 1878 (the tunnel alignment is on the north side of the northern side of the park's boundary wall, running beneath the gardens of the National Maritime Museum and Queen's House). In 1888 the park got a station of its own when Greenwich Park railway station was opened. The station was not successful, with most passengers preferring the older Greenwich station, and in 1917 Greenwich Park station and the associated line closed. Greenwich Park was used for outdoor London scenes including representing the street, Constitution Hill in the 2009 film The Young Victoria starring Emily Blunt and Rupert Friend. Geography The park is roughly rectangular in plan with sides 1000 metres by 750 metres and oriented with the long sides lying NNW to SSE. In what follows this direction is taken to be N to S for ease of exposition. It is located at grid reference . The park is on two levels, with a number of dips and gullies marking the transition between them. The lower level (closest to the National Maritime Museum, Queen's House and, beyond them, the Thames) lies to the north; from there a steep walk uphill reveals the southern part – a flat expanse that is, essentially, an enclosed extension of the plateau of Blackheath. Roughly in the centre, on the top of the hill, is the Royal Observatory. At the northern edge is the National Maritime Museum and Queen's House, and beyond those Greenwich Hospital. To the east is Vanbrugh Castle. To the south is Blackheath and in the south-western corner is the Ranger's House, looking out over the heath. To the west lie the architecturally fine streets of Chesterfield Walk and Croom's Hill (Pevsner 1983). Royal Observatory The Observatory is
