Two special anniversaries have been celebrated by one of Cambridge's biggest employers.
Employees' anniversary celebrations
Marshall's opened its doors to staff, their families and friends to help celebrate its 95th anniversary, as well as the 75th anniversary of opening its first airport.
The open day was also just four days after centenarian Sir Arthur Marshall, who inspired the building of the airport, was awarded the freedom of Cambridge.
Terry Holloway, group support executive with Marshall's, said: 'It's great timing.
'We hold a small private event such as this every five years or so.
'We place huge value on our people and it's an opportunity for us to allow them to bring friends and family to see their place of work and to provide them with a thoroughly enjoyable day out.'
Attractions included a funfair and small flying display of planes which have been linked to the airport through the years.
Guests on Sunday included the Mayor of Cambridge, David White and Cambridge city MP Anne Campbell. Actor Tim Bentinck, best known as the voice of David Archer in long-running radio soap The Archers, started the flying display.
Mr Holloway said: 'As on previous occasions, we are also using this event as an opportunity to work with a number of local charities to help them with their fundraising activities.'
Charities to benefit include Emmaus, The Fund for Addenbrooke's, Macmillan Cancer Relief, Save the Children and St John Ambulance.
Founded in 1909, the Marshall Group has a turnover of £2.5bn and over 5,700 employees. Headquartered on a 900-acre site in Cambridge, Marshall has three principal arms to the business: Aerospace and Defence; Property; and Ventures.
