This was originally up to the year 1877 a Free Grammar School endowed by Sarah, Dowager Duchess of Somerset, who in 1686 bequeathed the sum of £250 for the enlargement of the school house, and a further sum of £1,100 for the purpose of extending its benefit to all children of such inhabitants of the parish of Tottenham as were not possessed of an estate, either freehold or copyhold, of the annual value of £20.

The Savings Bank used to be held here every Monday evening, and was kept by Mr. Peter Rickards, the school master and clerk to Trinity Church. It was afterwards removed to the Post Office, where it now is, at the corner of High Cross-road.
