Rare early stereoscopic view of the first Territorial Capitol of Kansas, a stone structure located in Pawnee, within what is now Fort Riley. Erected in 1855, the building housed the inaugural territorial legislature of Kansas before political maneuvering led to its abrupt relocation. The image shows the stone building from a slight angle with its windows and doors appearing without glazing, suggesting disuse at the time of capture. A large sign above the entrance reads: “First Territorial Capitol / Kansas 1855 / Restored by Union Pacific Railroad / State of Kansas / Fort Riley.” Rows of tents or temporary structures can be seen in the distance, likely part of the surrounding military or rail encampments. A valuable image of Kansas's early political infrastructure, taken at a time when tensions over slavery and governance were rapidly escalating in the region.
