With a three-bay width and a nearly square shape, this two-story building also features an attic and a belfry that houses an enclosed stairwell, which is an unusual characteristic.

The exterior remains true to its original condition, while the interior boasts impressive paneling, the distinctive staircase mentioned earlier, and a spacious gallery with a railing.

3 does not belong to the church complex but rather served as the office for a gas plant that occupied half of the block during the late nineteenth and early twentieth centuries.

4, named the Eldridge Reeves Johnson Memorial Building, is a recently constructed structure featuring an attractive Georgian design.

The surrounding neighborhood, which was predominantly commercial and interspersed with deteriorating housing, has experienced a gradual revitalization since the demolition of the gas works in approximately 1955.

The ongoing improvement is further accelerated by the construction of a well-designed city police headquarters in close proximity and the scheduled development of a Federal Building directly across the street.

Another notable figure buried here is Colonel John Haslet, who commanded the Delaware Battalion during the Revolution until his demise at the Battle of Trenton in January 1777.

Together, the three units house numerous exhibits that offer insight into various aspects of Delaware life and history, attracting several thousand visitors each year.

Notably, the Johnson Building is dedicated to showcasing the history of sound recording as pioneered by the Victor Talking Machine Company.
