1955 Map of El Cajon

About this map

The San Diego River valley and surrounding foothills define this mid-1950s landscape, showing a transition from agricultural land to suburban expansion. The city of El Cajon serves as a central hub, flanked by the residential growth of Bostonia and La Mesa. Notable institutional sites like the Edgemoor County Farm and Gillespie Field occupy large tracts of land, while the San Diego and Arizona Eastern RR provides the primary rail link through the valley. Unique local operations such as the Maniscaleos Cactus Farm and the County Fairgrounds near Lakeside reflect the area's rural roots. Topographical markers like Mt Helix and Eucalyptus Hills frame the residential developments, which are supported by numerous neighborhood schools including Cajon Valley Jr High Sch and Grossmont High Sch. Religious and educational institutions are well-represented by St Francis Seminary and the Immaculate Heart Seminary located along the eastern slopes.
