By 1820 a small pueblo was developed below the Presidio using adobe bricks to build the homes. Fiestas were held in the plaza.
By 1846 the U.S. declared war on Mexico and a new constitution was written in 1849 and California was a state in 1850. By then the American flag was raised in the plaza and San Diego was incorporated as a city.From 1868-1874 the San Antonio and San Diego Mail Line stage coaches came through San Diego.There were a series of misfortunes with fire, floods a severe earthquake. In 1907 Spreckles bought the remains of La Casa de Estudillo and started to restore Old TownPaul and I visited several of the restored adobe buildings around the plaza. Many have small museums with docents who tell stories about the early history. Some of the buildings are used for shops with merchants in period costume who provide a peak into what life was like in the 1800’s.The cigar shop had an interesting collection of historic pipes.
The Wells Fargo Museum had early coins, a stage coach and mail route maps- click photo for details
