Following a proposal for a new site in 1835, a bank, to be built at 17 High Street, designed by architect Thomas Ustick Walter (1804–1887).

It was built in 1836 in the Greek Revival style at the cost of $33,000, and features a portico with four Doric order columns; the bank was subsequently altered in 1874, 1905, and 1928.

The previous building has since been rented to numerous individuals, although it still houses outdated equipment no longer used by the bank.

Initially, the bank assigned subscriptions to thirteen commissioners, although it decreased the number of individuals to be given stock to eleven in 1897.

Regular subscriptions to the shares were eventually established to the general population as well following the confirmation of the commissioners.

The stone used to build the bank originated at the Jacobs and Cornog marble quarry in West Whiteland Township.

The walls, which were built with marble, were overlaid with bricks; the western portico, which was lowered in 1928, includes four Doric columns.

Two vaults, originally placed on either side of the entrance hall, were converted into offices, and two rooms by the back of the bank were dismantled entirely as well as the stairways leading to them.

In 1854, Carl Stromberg recolored the ceiling with shades of blue, with "leaves, fruit, and flowers" painted on the walls' edges.
