Open green space is essential for our health and wellbeing, and we are delighted that more people than ever are now out and about enjoying OPT land.  With our commitment to the green agenda, OPT have no car parks, so why not take a cycle ride or a long walk.  Help us to keep our environment, our wildlife and you safe by considering a visit outside likely peak times.  All our green spaces are open. 

Help us to continue looking after these valuable green spaces by JOINING or making a DONATION now.

These fields were purchased by OPT in 2010 and 2011 and subsequently have been named Marston Hamm as 'hamm' is the Anglo Saxon term for an 'enclosure within the bend of the river'.

The fields are surrounded by ancient hedges and the River Cherwell on the south-west border.

OPT is working to restore species-rich grassland on this site, dredging ditches, erecting new gates, fencing and installing water troughs to enable Marston Hamm to return to the traditional management of grazing and hay cuts. 

In addition, OPT has constructed a punting pontoon on the river frontage and is working to create a permissive circular walk around the land.
