Lincoln Park was established during the founding of Greeley in 1870 as a successful expression of the town planning and urban design efforts of the city's founders. The 10-acre park was intended from the beginning to serve as the cultural and social focus of the city, reflecting the Union Colonists' vision of a cooperative community grounded in progressive irrigated agriculture, temperance, religion, and education. They placed the park at the center of town and envisioned it surrounded by governmental, religious, residential, and business buildings. Since its creation, the park has hosted festivals, celebrations, and memorials. In 1894, Potato Day turned the park into an agricultural pavilion where farmers displayed potatoes, cabbages, squash, carrots, and other produce for more than 6000 visitors. Among its notable features is the Pioneer Fountain, a stone structure built in 1907 and dedicated to Greeley's founders, containing sea shells and a petrified snake. Community festivals and celebrations continue there today, and Lincoln Park is listed on the Greeley Historic Register.
