BLENHEIM-PARK, a district (extra-parochial), within the liberty of OXFORD, though locally in the hundred of Wootton, county of OXFORD, containing 90 inhabitants. Blenheim castle was founded in 1704 pursuant to a parliamentary grant of £500,000, to be expended in raising the structure, and laying out the grounds, which, together with the honour of Woodstock, were bestowed on John, Duke of Marlborough, in testimony of national gratitude for his brilliant military and diplomatic services. The house was built from a design by Sir John Vanbrugh, and was called Blenheim from a village of that name on the banks of the Danube, near which this illustrious general obtained a signal victory over the French and Bavarians, on the 2nd of August, 1704, on which day annually, the inheritors of his Grace's honours and titles render at Windsor one standard, or colours, with three fleurs-de-lis painted thereon, as an acquittance for all manner of rents, suits, and services. It has all the appendages of a first-rate mansion, and the grounds and gardens are disposed with the most refined taste, and princely magnificence. The Roman road Akeman-street passes through the northern part of the park, being distinctly visible near the north lodge; and a little to the right of it, in the parish of Stonesfield, remains of Roman buildings were discovered in 1711 and 1779, and, a little further on, of a Roman villa, in 1813. For the early national events which took place at the old manor-house, see WOODSTOCK.
