National players, the Prime Minister and supporters of Desborough Bowling Club gathered for a milestone celebration on Sunday.
To mark the 50th anniversary of the club's indoor green being built, current and past members joined together for a special game.
While the club has been running since 1907, it was in 1966 the indoor green was built on the site of a tennis court.
This increased the club's membership as players could bowl all year round.
And the bowling club is still going strong with 508 members.
The majority of the members are retired but the club is broadening its reach with introductory sessions for seven local schools, including Newlands Girls' School and The Windsor Boys' School.
On Saturday, a Desborough team took on one from the English Indoor Bowling Association.
Roger Wyatt, 68, joined the club after retiring three years ago and is now the general secretary.
He said: "We all get on really well together.
"It is not just a bowls club it is a place where men and ladies can come in safety and enjoy the social club."
It was Roger that wrote to the Prime Minister to invite her to the event.
He did not expect for her to turn up and have tea at the club and her visit was kept secret from the members.
Bowlers were surprised to see a security dog scoping out the site in the middle of their game.
Club treasurer Peter Laban, 74, has been a member of the club for 21 years.
He said: "I think it is the members that make the club really.
"A lot of members who have moved away came back to celebrate with us today. It has been a very pleasant day."
The club is preparing to move to a new state-of-the-art facility in Green Lane, with work set to start in February. It is vacating its current home to allow for the redevelopment of the York Road opportunity area.
