AFTER two of the county's landmarks made a list of the 'most intriguing' places to be given listed status this year, the public have been asked to further enrich Oxfordshire's history.

A Roman military parade ground near Bicester and a concrete student block at St John's College made Historic England's list, published earlier this week.

Now the organisation has launched its 'enrich the list' feature which asks people to provide photos and information on the thousands of listed buildings in Oxfordshire.

The county has more than 12,500 listed buildings, scheduled monuments, parks and gardens.

Historic England said many of these remained relatively unknown.

Director of Oxford Preservation Trust, Debbie Dance, said it was a scheme the people of Oxfordshire would be delighted to help with.

She said: "It's fantastic to see this sort of initiative and I think it's something people in Oxfordshire will really get involved with, as there is huge interest in our heritage.

"Many people will have pictures and information on the history of listed buildings near them and it's great to have somewhere they can share it online."

"Many more buildings and monuments have been listed this year - the Sir Thomas White Building [at St John's College] really was long overdue but it's great to see a more recent college building being recognised for its contribution to the city."

Looking ahead to 2018, Mrs Dance said making sure Holywell Cemetery, which was at the centre of a planning appeal regarding student flats next door, was listed and protected going forward.

She also urged residents to add to the city council's Oxford Heritage Assets Register, which offers protection for local sites that may not be able to received national protection.

Historic England's 'top 20 intriguing' listed buildings also recognised the significance of the Alchester Roman Parade Ground in Merton.

The Roman town of Alchester, the largest in Oxfordshire, lies 1.5 miles from Bicester and was founded in the mid-1st century.

Work on the Oxford-Bletchley railway line in 1848 revealed the town's cemetery and aerial photographs in the 1960s led to the belief it was a former fortress.

The photographs also showed the parade ground, access road and marching camp which would have been used to train infantry and cavalry.

This was confirmed by excavations led by archaeologist Professor Eberhard Sauer, who contends Emperor Vespasian may have used the site as his headquarters when he was a military commander.

In its reasons for giving the site 'schedule monument' Historic England said: "It is a rare site-type, believed by some to be one of the earliest examples in the Roman Empire, and one of only a very small number known and designated in Britain.

"The buried remains of the ditches and Roman access road survive well, and it is believed that some of the gravelled surface remains in situ."

It added: "The likely association with Vespasian and chronological relationship with a temporary marching camp, which probably predates the fortress, enhances the historic importance of the monument."
