Pike's Stockade, Historical frontier stockade in Sanford, Colorado, United States.

Pike's Stockade is a reconstructed wooden fort with a square design and two bastions positioned along its northern side near Sanford, Colorado. The site includes an underground tunnel that runs beneath the walls, serving as an access point to the interior structures.

Zebulon Pike's expedition, sent by President Thomas Jefferson after the Louisiana Purchase, left St. Louis in July 1806 and reached this spot on the Conejos River in January 1807. Pike raised the American flag on Spanish soil and built the stockade as a defense against Spanish attack. On February 26, 1807, 100 Spanish cavalry arrived and summoned him to Santa Fe; Pike and his men were released in July 1807.

The site's name comes from Zebulon Pike, who raised the American flag here on Spanish soil in 1807. Pike's written description of the original cottonwood stockade guided the reconstruction, which uses oak instead. Visitors can see the two bastions at the northern corners and enter through a tunnel under one wall, as Pike's men did.

The site is located about 8 miles northeast of Sanford and can be accessed via County Road 24. Informational markers throughout the grounds explain the historical context and help visitors understand the different features of the fort.

The fort was reconstructed not as an exact replica but with modern accommodations such as the underground tunnel built into its design. These additions allow visitors today to explore the interior while preserving the historical structure itself from excessive wear.
