In the 1890's, the Rocky Hill Quarry, located on what is now called Rocky Ridge, produced trap rock which was used primarily for road building.

Much of the heavy labor was performed by Irish immigrants. In 1876, the first St. Lawrence O'Toole Church was constructed to meet community needs.

At the turn of the 20th century, trolley lines along Zion Street, Fairfield Avenue and New Britain Avenue opened up the neighborhood for residential development.

By 1912, the Rocky Hill Quarry had become a park, that is today known as the Thomas Hyland Memorial Park. The park provides a playground and sports fields for area families.
