Richfield is an inner suburb of Minneapolis, and it started as a farming community back in the 1850s. In 1858, Minnesota was admitted to the Union, and the residents of the farming community named themselves Richfield after the fertile soils around them. They went through several growing pains before becoming more commerce-focused. The Richfield Chamber of Commerce was formed in 1955, and they have been very involved in developing and shaping Richfield. There are roughly 35,000 people and 10,000 single-family homes in Richfield. Most of the homes were constructed in the 1950s, and over the next few decades, 5,000 apartments were built. The people are diverse, and the homes are being remodeled and updated from small post-World War II houses to larger and more modern homes. Best Buy is one of the most well-known businesses in Minnesota, and it is headquartered in Richfield. The headquarters moved there in 2003, and they have been the top employer in Richfield ever since. Richfield still has plenty of nature that is pristine and serene. The most notable is the Wood Lake Nature Center, which is a 150-acre nature preserve and is run by the city. It has Wood Lake, of course, and it also has restored prairie habitats, lowland forests, and a marsh with cattails. There are walking trails, an outdoor amphitheater. and a picnic area. There is also an Interpretive Center that has classes taught year round by naturalists for children and adults. It opened in 1971 as one of the first urban nature centers in the country, and it now has 200 kinds of birds and 30 mammals.
