This fine memorial in St Helens Church, might be easy for scholars of Abingdon School to translate.

I guess the general sense is that John Roysse founded Abingdon School in 1563. So, the question for me, is why are they celebrating their 750th year?

The school website says:
In 1563, the sixty-three year old John Roysse gave £50 to the Corporation of Abingdon and specified that it should be used to build a schoolroom that was to be sixty-three feet long for sixty-three free scholars.

John Roysse was helping to refound a grammer school already mentioned in earlier documents. The first mention was the endowment by Abbot John de Blosneville for the support of thirteen poor scholars in 1256.

Abingdon School moved from the Roysse room near the Guildhall to the present site in 1870. It is built in the style of the surrounding houses on Park Crescent (one is pictured). This style is well known from the large victorian houses in North Oxford.

Looking around the school, what is interesting to see is how much green grass they have available for sports activities. This particular stretch of grass has been marked out as a running track. Trinity Church is on the far boundary.
