Council chairman Mac McGuire buried the time capsule that also included postcards from councillors, staff.
It also includes the front pages from newspapers in Cambridgeshire to show people what is in the news on the day.
Face masks and a home testing kit have also been included to show some of the elements of living during a pandemic.
The time capsule has been buried in the staff seating area outside of the new headquarters with an engraved slab marking its position.
The aim is that there will be a ceremony in 2046, 25 years after the time-capsule has been buried.
“This time capsule gives us an opportunity to show staff, councillors and the public in 2046 what life was like in 2021 during a pandemic and our hopes and dreams for the future", said Cllr McGuire.
