The Green Flag Award is a sign of a well-managed, clean and safe park.
In total this year 1,797 parks, cemeteries, universities, museums, hospitals and shopping centres have met the criteria demanded by the award. In 2016, 1,686 awards were made.
Among this year’s new entries are the community garden at London’s Tate Modern and the grounds of the National Maritime Museum in Greenwich.

Also raising the Green Flag for the first time this year is Milton Keynes which, as it celebrates its 50th anniversary, is celebrating a Green Flag Award at the Milton Keynes linear parks.
Each year, more countries are adopting the Green Flag Award as the standard for its parks and in 2017 there are Green Flags flying over parks in Spain, Sweden, Australia, New Zealand, the Republic of Ireland, Germany, the Netherlands and the United Arab Emirates.
Keep Britain Tidy chief executive Allison Ogden-Newton said: "Research shows that parks are a vital and valued resource in communities across the UK and we are delighted that so many of them are meeting the high standards demanded by the Green Flag Award.
"But we cannot be complacent. We know that budgets are being squeezed in local authorities across the country and we must be vigilant to ensure that everyone, where ever they live, has access to the very best parks and green spaces."
This week is also Love Parks Week.
