Located in the heart of Willamette Valley, Albany is known for having the most varied collection of historic buildings in Oregon. The city's Monteith, Hackleman and Downtown Commercial Districts, each listed on the National Register of Historic Places, feature 350 historic homes. Those interested in history and architecture marvel at the diversity of the city's structures, which provide examples of every major architectural style popular in the United States since 1850. In addition, eight historic covered bridges dating back to the 1930s are located nearby. The last Saturday in July, Albany hosts the Summer Interior Homes Tour, which features tours of museums, historic churches and homes, as well as hay-wagon and trolley rides. Throughout the year, visitors enjoy perusing the cultural artifacts that are on display at the Albany Regional Museum. The variety of interesting shops, dining opportunities and recreational activities that complement the city's rich history make Albany a destination well worth discovering.
