The park surrounds the house extending mainly to the north, west and south. Little is known of the early landscaping, although Capability Brown was asked in 1771 and 1772 to propose 'alterations'. His work included the extension of Newsham lake to the north of the estate. The late 18th century Newsham Bridge may be of his design (but see PRN 55672). Brown proposed further alterations in 1778. Much tree-planting took place in this period. Brown may also have designed the arabella aufrere temple built c.1787, 1km south of Brocklesby Hall. This is within the belt of woodland, c.200m wide, which runs south from the hall for 2km to join the 100ha mausoleum woods in the southern part of the estate. There are other features in the estate including the Pelham Mausoleum, by Wyatt, 1787-92, based on the temple of the Sybil at Tivoli in Italy. Gardens and park are on the Register of Parks and Gardens, as grade I. {1}{2}{3} In August 1914, at the start of the First World War, part of the park was used as a training camp for the 10th (Service) Battalion of the Lincolnshire Regiment (The Grimsby Chums). The battalion left Brocklesby in the spring of 1915 moving to other camps in England prior to their transfer to France in January 1916. {4}
