Milton Mausoleum sits close to the A1 Great North Road roundabout at Markham Moor in Nottinghamshire.

Built for the 4th Duke of Newcastle by Robert Smirke, architect of the British Museum, the Mausoleum unusually incorporates a parish church in the design.

Now in the care of the Churches Conservation Trust, the Mausoleum is no longer used for worship, although it remains consecrated.

The Friends of Milton Mausoleum hold a series of open days and events throughout the year to ensure that the building remains used and cared for and to tell the, sometimes tragic,  story of the 4th Duke and his family.

Summer Openings 2022.

We are pleased to let you know that we will begin our Sunday openings on May 1st from 2pm – 4pm and these will continue until the end of September.


Milton Mausoleum, or to give the full title “The Newcastle Mausoleum and All Saints Church, Markham Clinton” is that stunning and intriguing building on the hill between Milton and West Markham, still visible from the A1.

Built by the 4th Duke of Newcastle to honour his beloved wife, following her untimely death in 1822, it served as the Parish Church for Markham Clinton from 1833 until 1949. The marriage of Henry to Georgiana Miller Mundy in 1807 was very much a love match and they went on to create a grand family home at Clumber Park and produce 14 children. When Georgiana gave birth to twins in September 1822 the couple had tragically lost their eldest daughter just months before in the May. Following the birth of her twins (a stillborn girl and a boy who lived for 10 days) Georgiana succumbed to infection and died. A devastated Duke commissioned the building as a memorial and a place of worship. Sir Robert Smirke, designer of the British Museum was commissioned for the building and leading sculptor, Richard Westmacott executed the most stunning and lifelike monument to the Duchess and her twins, not forgetting their 14 year old daughter, Anna Marie.

The “Friends of the Mausoleum” was formed in the spring of 2015 with the aim of bringing the building back into use by the community. At its core are the team of volunteer stewards who open the Mausoleum to the public every Sunday afternoon from May to September. Put a visit in your diary for 2020 – come and see this treasure for yourself!

Since the 1970s the Mausoleum has been in the care of the Churches Conservation Trust (CCT), but it is only since 2015 that community events have been held – gigs and concerts; recitals; tea parties and talks … This year’s “piece de resistance” was a black tie concert “On Golden Hill” with wine and canapés on the north lawn. 2019 sees the 50th anniversary of the CCT and it chose 50 of its 350 plus churches to host an event. Milton Mausoleum was one of them, a testament to the work of the team and the support of the local community for our events! The Duchess would ride from Clumber to the top of her “golden hill”, perhaps her first ride up there was at harvest time? And so, a 50th anniversary title could not have been more apt!

To bring the building into practical use today we have been fund raising for the installation of electricity and with the very hard work of the fundraising team and the generous support of the community we have now completed this work. We can now think about what use the community can make of the Mausoleum… the possibilities seem endless.
