The Watertown Arsenal was the first major engineering testing laboratory in America. It was created to store and manufacture cutting-edge military technology and weaponry. The United States Army Research and Materials Laboratory continued to use the site until 1989, employing soldiers and civilians to produce and test artillery.

This furnace was the focal point of a pre-Industrial Revolution industry town, one of hundreds of furnaces that thrived and failed in the 19th century. The Maryland Iron Company (incorporated 1828) built this furnace along the Nassawango Creek roughly four miles northwest of the Pocomoke River to produce pig iron by the cold-blast process. In 1836-37 the furnace changed ownership several times, until Thomas Spence of Worcester County purchased it and began producing pig iron at a rate of 700 tons a year. Spence is credited with the installation of the hot-blast stove.

This ironworks exemplified the adaptability required for industrial survival in a dynamic technical environment. It was a major western producer of mechanical equipment used in mining (especially large hydraulic machines), ship propulsion, irrigation, power generation, optical telescope mounts, and nuclear research.

This elegant cast iron arch bridge designed by Scotland's famous Thomas Telford was built from 1812 to 1814. It is the earliest surviving example of a portable lattice-braced standard type that Telford developed for use at wide and deep water crossing sites unsuitable for masonry spans. At least 10 of these bridge types were erected throughout Britain between 1814 and 1829.
