History of Mountainside

Mountainside, New Jersey, is a borough with a rich history that dates back to the early 18th century. Nestled in Union County, it was originally an area inhabited by the Lenni Lenape Native Americans. European settlers began to arrive in the 1720s, establishing the foundations of the community we know today.

The name "Mountainside" was derived from its picturesque location at the base of the Watchung Mountains. This scenic backdrop has long been a draw for residents seeking a tranquil environment close to nature. The borough was officially incorporated on September 25, 1895, from portions of Westfield Township, making it one of the state's earlier communities.

Throughout the 19th and early 20th centuries, Mountainside remained largely rural, with agriculture playing a significant role in local livelihoods. However, the post-World War II era brought significant change as residential development increased, transforming the borough into a suburban haven. The construction of Route 22 in the 1930s also contributed to the area's growth, improving access and attracting new residents.

Today, Mountainside is known for its small-town charm, excellent schools, and community spirit. It boasts a variety of local parks, such as the expansive Echo Lake Park, and historical sites, including the Hetfield House, which serves as a testament to the borough's enduring legacy. For those living in or considering a move to Mountainside, the borough's history is a source of pride and a foundation for a vibrant community life.
