What was the last name of the person who had a large pond or lake dug?
In 1690, Sir John Brownlow was granted permission to enclose an area of 1,000 acres (4 km²) to transform into a park, with a grant to keep deer. There is evidence to suggest that some of this area had been a park since at least 1580. The park was laid out with avenues, including the still surviving Eastern Avenue which led east from the house. Brownlow also had a large pond or lake dug and planted 21,400 ash trees, 9,500 oak trees, and 614 fruit trees. It is thought that William Winde may have advised on the layout of the gardens. Closer to the house were a series of more formal gardens, including canal ponds bordered by plantations containing symmetrical walks resembling the "rond-points" (circular clearings in a garden from which straight paths radiate) introduced by the landscape gardener André Le Nôtre. By the end of the eighteenth century, these formal parterres had been removed and the canal ponds filled in.Sir John Brownlow was succeeded at Belton by his brother, who was content to permit Brownlow's widow, Alice, to remain in occupation. She spent the remainder of her life at Belton arranging advantageous marriages for her five daughters. On her death in 1721, the house passed to her husband's nephew (and her son-in-law) Sir John Brownlow III (later Viscount Tyrconnel). Tyrconnel, a dilettante of no great intellect, was responsible for many of the architectural features which survive in the park and garden. Between 1742 and 1751, a series of follies, including a Gothic ruin, a cascade, and a prospect or belvedere known as the Belmount Tower, were constructed for him. When built the tower had two small wings flanking each side, since removed.John Cust, 1st Earl Brownlow, owner of Belton House from 1807–1853, commissioned the architect Anthony Salvin to undertake improvements to the Estate in 1838. Salvin's additions included a public house, estate cottages, a hermitage and the boathouse.
