The Oldest Building in Every State

Wyoming - Fort Laramie

Wyoming - Fort Laramie

Fort Laramie in Goshen County is one of the oldest buildings in Wyoming and it has gone by many names. Founded in 1834, as a private trading post called Fort William, it was sold by William Sublette and Robert Campbell to a local fur trader, a year after it was built. It was sold again to the American Fur Company in 1836, which constructed a new fort, named Fort John, to replace it.

 In 1849, the United States Army purchased the fort to protect wagon trains traveling in the area. The fort, which was often referred as the "Fort John at the Laramie River" gradually became known as Fort Laramie. Today, it is preserved as the Fort Laramie National Historic Site.

South Dakota - Fort Sisseton

Fort Sisseton in Lake City, South Dakota was established in 1864. Now named after the Sisseton tribe, it was once called Fort Wadsworth. The site was ideal because of its ample supply of limestone and clay needed for making bricks, plus the landscape provided a natural defense. A nearby lake provided water to soldiers, while trees provided timber for fuel.

Now part of the Fort Sisseton Historic State Park as of 1959, the area is open to travelers and locals. It is now part of a scenic park that is home to the historic fort.

The Block House in Claymont, Delaware was constructed in 1654 by Johan Risingh. As Governor of New Sweden, Risingh had acquired the land from Chief Peminacka of the Minqua tribe. Originally, the house had been designed for defense but that didn't stop the Dutch West India Company from taking over the house. In 1671, the Block House was attacked by Native Americans, and in 1777, was captured by British forces during the American revolution.

The Block House is quite small. It consists of only one room with an upper and lower level. A large fireplace and living quarters for Robinson House cook are featured. But while the home may be small, the house is rich in history.

Montana - Old Fort Benton Blockhouse

Montana - Old Fort Benton Blockhouse

The Old Fort Benton Blockhouse is yet another fur trading relic, located in Montana. Built in 1847, it was established by Alexander Culbertson of the American Fur Company. Upon orders to relocate the existing Fort Benton, he disassembled the log building, bastions and walls of the fort and moved them down the Missouri River. Reassembling them at a new site, he called the new structure Fort Benton.

With an area over 150 square feet, Fort Benton was massive, designed not only for trading but defense as well. A 14ft high wall connected the buildings. Unfortunately, most of these structures are not standing except for the northeast bastion. This final remaining structure is preserved for future generations.

Nevada - Old Mormon Fort

The Old Mormon Fort in as Vegas, Nevada is perhaps the most interesting thing the area has to offer, especially if you love history.

The Molalla Log House is one of the most mysterious buildings in America, in addition to being one of the oldest. Believed to be as old as the year 1799, the house predates the Lewis and Clarke expedition in 1804.  Because it is unlike any cabin built by the pioneers, historians have suggested that it was likely built by Russian settlers sent by Catherine the Great.

The materials used to build the house have been moved to Hopkins Demonstration Forest where it will be rebuilt. Although it was scheduled to be completed by the end of fall, it is difficult to say whether it will be finished on-schedule, considering COVD-19.

Mission San Juan Capistrano is the oldest Spanish mission in the state of California. It can be found in San Juan Capistrano, Orange County, California where it was built in 1776. Years later in 1833, the Mexican government secularized the mission but it was turned back into a Roman Catholic Church by the United States government in 1865.

Although natural disasters have inflicted much damage, Mission San Juan Capistrano has been meticulously restored over the centuries. Because of its rich history and incredible beauty, the San Juan Capistrano mission continues to fascinate California residents and tourists.
