1. Historic Rancho Boundary Line Marker
You are standing at the point of the blue arrow, which lies on the border between the San Pablo and El Sobrante Ranchos. Both grants were made by the Mexican Government to members of the Castro family in 1834 and 1841, respectively. On your right is the San Pablo Rancho; to your left is the El Sobrante Rancho. The line runs along the ridge separating the valleys through which run Appian Way and May Road. As you can see, much of what we think of as El Sobrante, including the entire downtown, lies within the boundaries of the San Pablo Rancho.
