This year The Daily Transcript is celebrating its 120-year anniversary and in tribute, we offer a special feature in this year's SourceBook: Milestones & Landmarks. In this section we spotlight 120 landmarks within San Diego County and identify milestones that helped shape the future of North, Central, South and East County.

The early years of North County are marked by its ranches and missions, many of which still stand today. When the California Southern Railway, a branch of the Santa Fe, arrived with stations in Oceanside, Fallbrook and Temecula, the region began to grow and prosper.

From historic battle sites to the nation’s busiest military base to scenic parks, North County’s landmarks are representative of the area’s past and future. Thirty of North County’s landmarks are described -– just a sample of the region’s many points of interest, old and new.

Horton, Spreckels, Kettner, Scripps and Hahn. Names like these shaped central San Diego and are still recognized today. And as today’s leaders and developers look back after decades of expansion, neighborhoods from La Jolla to Mission Valley to East Village are becoming denser with the helping hand of mixed-use development.

Central San Diego is rich with history and culture, and many landmarks can be found simply by taking a trip through Balboa Park, Old Town or along the coast. Some landmarks hold historical significance, others are noted for the way they helped shaped the future of the region, and the newer ones may not have historical significance yet, but hold promise. The following are 50 Central San Diego landmarks.

South County has always been a vibrant region rich with culture. The area hit the ground running with the arrival of the Santa Fe Railroad in the 1880s and never looked back. The Sweetwater Dam and a luxury resort called the Hotel del Coronado soon followed, and people flocked to the region filled with the promise of opportunity.

South County’s landmarks symbolize the region’s history and growth. Several historic names have left their legacy for future generations to enjoy – names like Spreckels, Granger and Kimball. Other landmarks allow visitors to relax, be engaged or simply entertained. The following are 20 noteworthy South County landmarks. But perhaps more importantly, the face of South County is changing so dramatically that it is safe to say more will be added in the years to come.

The buying and selling of land, as well as the discovery of gold shaped the early years of East County. Soon after, water and the railroad arrived, and the land boom really took off. Today, the eastern parts of East County remain fairly rural with lots of undeveloped land. But the western end has seen residential and commercial developments crop up, making it an affordable place in which to live -– relative to other parts of the county -– work, and conduct business.

East County contains a wide variety of landmarks. From the first irrigation project on the West Coast to the greatest gold mining camp in the region and, in more recent times, casinos, East County has found its own way to make its mark on the county.
