full_context: Document 1: Greenwich Cricket Club: Representing Greenwich which was then in Kent, the original Greenwich Cricket Club was prominent in the 18th century, taking part in known important matches from 1730 to 1767. According to surviving records, the team used a now unknown location in nearby Blackheath for its home matches. Greenwich teams are recorded, either individually or jointly with other clubs, in eight known important matches.
Document 2: Chelsea Common: In the 18th century, Chelsea Cricket Club was prominent for a time and played its home matches on what was then Chelsea Common, an area that virtually disappeared under building work in the 19th century. Records have survived of five important matches between 1731 and 1789 which either involved the Chelsea club or were played on the common. The first, played on the common for the high stake of 50 guineas, was Chelsea v Fulham on Tuesday, 13 July 1731. Fulham won. There was a return at Parsons Green on Tuesday, 10 August 1731, which Fulham won by 3 runs. On Tuesday, 26 June 1733, Fulham again hosted Chelsea at Parsons Green, this time for 30 guineas, but the result of this match is unknown. On Monday, 16 August 1736, there was an inter-county match on the common between Middlesex and Surrey. The stake was 50 guineas and Middlesex won by 9 runs. The last match found in the records was on Thursday, 10 and Friday, 11 September 1789 when Chelsea played Marylebone Cricket Club (MCC) in Marlborough Gardens, Chelsea. This match, which was of dubious status, was probably drawn after a postponement.

The final important match at the ground, in 1892, was between the Lyric Club and the Marylebone Cricket Club. The ground was located within the grounds of St Ann's House, which in the early 1900s it was built over. The approximate location of the house today would be near Lyric Road and St Ann's road, which are near the River Thames.
