The Center begins its search for the remains of Tucson's Presidio Walls. Initial construction of the Presidio took place between 1776 and 1783. The last standing segment of the wall was destroyed in 1918. Test trenches in the courtyard of the current Pima County Courtyard revealed remnants of the eastern presidio wall. |
