History

Horsham Township was established in 1717 by Samuel Carpenter, who was from the town of Horsham in Sussex, England. The Township, incorporated in 1717, is one of the oldest original municipalities in Montgomery County. Although it retains the word “Township” in its official name, it has been governed by a Home Rule Charter since 1975 and is therefore not subject to the Pennsylvania Township Code.

Horsham Township is named after the town of Horsham in West Sussex County, England. Horsham is one of several townships in Montgomery County whose name and size were determined by master survey lines drawn by William Penn’s engineers as they first plotted this part of the colony for sale and settlement. Parallel lines, projected at intervals of a mile and a half and extending in a northwesterly direction from settlements along the Delaware, served not only as base lines for measurement of individual land grants but also as courses for future highways. County Line Road, Horsham Road, and Welsh Road are examples of highways thus laid out. The effect of these survey lines upon the development pattern of Eastern Montgomery County is very much in evidence today.
