All for Colchester, it seems fitting with lots of history there
Milton Keynes can get in the bin.
Old article, it mentions it has a tree cathedral, for those like myself who don’t know what a tree cathedral is see paras below from the park trust website.
There is a unique cathedral in Milton Keynes, not made of bricks and mortar but of bark and leaves. The Tree Cathedral at Newlands is based on the outline of Norwich Cathedral and was designed in 1986 by landscape architect Neil Higson.
Different species of trees were chosen to represent the different sections of the Cathedral. Hornbeam and tall-growing lime for the nave, evergreens to represent the central tower and spires and flowering cherry and apple as a focus in the chapels. In springtime colourful bulbs represent the sun shining through stained glass windows onto the ground.
The Cathedral has a mix of evergreen and deciduous trees, meaning its visually stunning throughout the year.
The feeling amongst many people is that a city can be considered exactly that, a city, if it has landmarks that are reflective of a city such as a cathedral, university, a type of local government or a large population.
Whilst all of these factors may contribute to being able to apply for city status - ultimately, the decision lies with the Queen.
But Milton Keynes does have the University of Bedfordshire, Milton Keynes campus and the largest population in Buckinghamshire.
In terms of Cathedrals, it has the Tree Cathedral - the only municipal tree cathedral in the country.
