Eagle Bluff Light

The Eagle Bluff Light, also known as Eagle Bluff Lighthouse, is a lighthouse located near Fish Creek in Peninsula State Park in Door County, Wisconsin. Construction was authorized in 1866 by President Andrew Johnson, but the lighthouse was not actually built until 1868, at a cost of $12,000. It was automated in 1926. The former lighthouse keeper's home has been a museum since 1963. Park admission and a donation is required to tour the lighthouse.

State parks or provincial parks are parks or other protected areas managed at the sub-national level within those nations which use "state" or "province" as a political subdivision. State parks are typically established by a state to preserve a location on account of its natural beauty, historic interest, or recreational potential. There are state parks under the administration of the government of each U.S. state, and of some states of Mexico. The term is also used in Australia, though the distinction between state and national parks there is different. The Canadian equivalent term is provincial park. Similar systems of local government maintained parks exist in other countries, but the terminology varies.

State parks are thus similar to national parks, but under state rather than federal administration. Similarly, local government entities below state level may maintain parks, e.g., regional parks or county parks. In general, state parks are smaller than national parks, with a few exceptions such as the Adirondack Park in New York and Anza-Borrego Desert State Park in California.
