Church Street sweeps to the west a little further on, and at the corner stands a Roman Catholic orphanage, where fifty or sixty girls are provided for. There is a chapel within the walls, and night-schools are held, which are attended by children from outside. The continuation of the road northward, which becomes Brunswick Gardens, was made in 1877, and as the old vicarage stood right in the way it had to be pulled down. Bowack says that the vicarage was "valued yearly in the Queen's [Queen Anne's] Book at L18 18s. 4d., but is supposed to be worth near L400 per annum." In Vicarage Gate northward is a small church (St. Paul's) served by the clergy of St. Mary Abbots. The origin of the name Mall in this part of Kensington is not definitely ascertained. It of course refers to the game so popular in the reign of the Stuarts, and there may have been a ground here, but there is no reference to it in contemporary records. In the Mall there is New Jerusalem Church, with an imposing portico. It was formerly a Baptist Church, and was bought by the Swedenborgians in 1872. A bright red-brick church of the Unitarians is a little further on. Behind the Mall is Kensington Palace Gardens--really a slice of the Gardens--a wide road with immense houses, correctly designated mansions, standing back in their own grounds. This road is only open to ordinary traffic on sufferance, and is liable to be closed at any time. The part of Kensington lying to the west of Church Street and extending to Notting Hill Gate was that formerly known as the Gravel Pits, and considered particularly healthy on account of its dry soil and bracing air. Bowack says that here there are "several handsome new-built houses, and of late years has been discovered a chalybeate spring." Swift had lodgings at the Gravel Pits between 1712 and 1713, and Anne Pitt, sister of Lord Chatham, one of the bright bevy of Queen Caroline's maids of honour, is reported to have died at her house at the Gravel Pits in 1780.
