Waterperry Gardens near Wheatley is now closed due to the coronavirus lockdown.
Regular visitors will be looking forward to relaxing there when it reopens.
In 2019 staff and volunteers at the gardens were delighted to welcome Gardeners' World presenter Rachel de Thame for a special occasion - the opening of a new viewing tower.

Funded by the School of Philosophy and Economic Science, the tower was designed by David Hockley and built by John Franks and is now open for visitors to enjoy.
Its wooden frame came from an oak tree that had to be cut down in the garden three years ago.
After years spent seasoning the wood for the tower's eventual construction, people can climb the spiral staircase and peak over the walls of the garden to view the eight acres of gardens beyond.

Ms Thame, who presented on BBC2’s Gardeners' World, said during her visit: “It was such a joy for me to come to Waterperry and see the walled garden and tower for myself.
Pat Havers, head gardener at the centre, added: “Today has been a beautiful finale to the completion of this tower.
“Personally it has been made more special to have Rachel open it for us.”
The garden's website said: "Following recent government announcements and direction regarding Covid-19 and with the safety of visitors and staff uppermost in our mind we have decided to close the whole estate and be part of the solution to this situation rather than part of the problem.

"This was a tough decision to make as we know that beautiful gardens such as ours are a source of inspiration and mental wellbeing for all.
"However the very strong direction to stay local for exercise has to be taken into account and we do not want to encourage unnecessary travel.
"We hope to see you again soon."
The garden shop remains open for online and telephone sales, with some local deliveries being made.
