Moorpark CA was founded in 1900 and for many years the railroad was the lifeblood of the community. A visit to downtown Old Town Moorpark with its historic buildings and avenues of pepper trees will transport you back to these early days. One interesting fact about Moorpark CA is that it was one of the first cities in the country to use nuclear power. The reactor was built at the nearby Santa Susana Field Laboratory.
