The manor remained in royal ownership until 1154, and then passed back and forth between royal and private ownership several times. Wendover was granted a market charter in 1214, and had become a borough by 1228, although it does not appear to have achieved any degree of self-government. It is likely that around this time the focus moved north to its current location, allowing the market to cater to traffic on the road running along the Chilterns between Chinnor and Tring, as well as that crossing the Chilterns between London and Aylesbury. The current layout of the older parts of the town show clear signs of medieval town planning, especially the presence of long, narrow and rectilinear burgage plots.
