Wildomar is a community of old and new, more mature homes and acreages with horses and other animals mixed with more modern housing tracts. Nestled between the cities of Murrieta and Lake Elsinore, Wildomar officially became a city on July 1, 2008, at that time home to about 28,000 residents.

The name Wildomar was coined from the names of its three founders -- the WIL from
William Collier, the DO from Donald Graham and the MAR from Margaret Collier Graham.

Wildomar had been an outpost for the pony express for the Butterfield Stage, and in the early part of this century, a stop for the Southern California Railroad. After the tracks washed out, growth in the area slowed and Wildomar remained a farming and ranching area, including a large number of horse ranches.

Construction of the I-15 freeway brought urban-type growth to Wildomar, which led to the mixture of urban and rural.

Wildomar Incorporation Now, commonly known as WIN, led the effort to incorporate.

Its office was in a small, unassuming historic building near the corner of Mission Trail and Corydon. It is one of the oldest public buildings in the area.

Currently leased by the Wildomar Chamber of Commerce, the building has served the community in one capacity or another for over 100 years. Originally on Lemon Street, the building was moved to its present location in 1895 selected because the railroad tracks ran behind the building. The building was to be a stop for the railroad. Once the railroad no longer ran through Wildomar, the building found other uses. In 1993, the Animal Friends of the Valleys and the chamber brought the building back into a serviceable condition. These two agencies have shared the building ever since.
