The second stage in Rosarito’s evolution, referred to as the "Misional", began with the arrival of the Spaniards in 1533. So named because it marked the establishment of missions throughout the peninsula and the evangelization of the native tribes. A total of 28 missions were founded by the Jesuits, Dominican and Franciscan monks in what we know as Baja California. 

 In 1767 the Jesuits were expelled from Mexico in a political-religious decision, the Franciscans were asked to take over the administration of the missions. In 1772, a concordat (agreement) was signed between the King of Spain -with the support of the Viceroy of New Spain (Mexico) and the Pope- and the leaders of the Dominican and Franciscan monks resulting in the division of California in 1773, using the local mountain range that meet the sea at Calafia. The Palou Frontier was establish as the dividing line between Nueva (new) or Alta (upper) California and Antigua (old) of Baja (lower) California. 

 The Franciscans took control of Alta California and everything north of the Palou Frontier (including what we now recognize as the State of California, USA) was their domain. Alternately the Dominicans controlled everything south of the frontier in Baja California. Fifteen years later, en 1788, the De Sales Frontier was establish and the boundary between the two Californias was relocated to the site of the Rosarito Creek. 

 The third stage in Rosarito’s history began with the establishment of the big Ranchos. The property of El Rosarito Ranch, granted to don Jose Manuel Machado on 1825, stands out as the first in the area. Subsequently his son, don Joaquin Machado, applied for tittle to the land to then President Porfirio Diaz, and, on May 14th, 1885, tittle was granted and registered in la Ensenada de Todos los Santos, then capitol city of Baja California. May 14 is now recognized and celebrated as Rosarito’s Foundation Day by the Historical Society of Rosarito. 

 The fourth stage of Rosarito’s history is known as the TOURISTIC. It began with the stablishments of a place by the name or Rene’s in 1925 and the Rosarito Beach Hotel in 1926. Rosarito was visited by tourist since 1874 (San Diego Union), attracted by hunting (dear, quail and rabbit) and fishing (lobster, abulone). 

 The "Ejidal" and fifth stage in Rosarito’s history began with the inception of Ejidos (common land for farming) when, on August 17, 1930, General Lazaro Cardenas, then President of Mexico, issued a resolution granting 4,671 hectares (over 10,000 acres) of land to a community of local farmers known as Ejido Mazatlan. 

 The beginnings of urbanization in 1950 marks the sixth stage in Rosarito’s development with the planning and construction of streets and city blocks. As land sales soared, coupled with the construction of small restaurants, some shops and two hotels, the city began to take shape. 

 In the 1960’s Rosarito entered the commercial/industrial era with the constructions of a huge thermoelectric power plant and the later installations of Pemex, the Mexican Gas Company. 

 This seventh stage in Rosarito’s evolution was marked with further construction and the development of shopping centers and more restaurants and shops were stablished along the main street. This street has been renovated and enlarge to encompas four lanes and a lighted meridian strip and, in 1889, was officially designated Boulevard Benito Juarez. 

 During the seventies and early eighties, Rosarito’s growth was moderate but constant. The mid-eighties, however, was marked with the strong development of tourist related busnisses of obviously considerable investment. Available hotel rooms in Rosarito were up from 350 to 700. 

 In the early 1990’s appreciable economic growth was been achieved by the construction and competition of numerous hotels, condominiums and shopping centers. 

 Beginning the first day of December 1995, Rosarito converts from a Delegacion (suburb) of Tijuana, into the fifth Municipality (county) of the State of Baja California, being this the eight stage of the history of Rosarito. Now Rosarito has two "Delegaciones" (suburbs): Plan Libertador, just north of town, and Ejido Primo Tapia, south of town. With these two suburbs, Rosarito encompasses nearly 40 miles of coastline and the population has grow from 28,000 to more than 100,000 residents, according to 1992 census figures. 

 In addition to the natural appeal of Rosarito’s coastline, tourists are attracted by the more than 30 yearly sporting/touristic events, specifically designed for the visitor’s participation. The traditional Rosarito-Ensenada bike ride, for example, has drawn up to 19,000 entrants and finally became so pupular that there are now two rides, one in April and the original held in September. Three-wheeler competitions on the very famous Cantamar sand dunes in Primo Tapia, Bi- and Tri-athalons, 5 and 10K runs, nice volleyball on the beach tournaments, sand castle contests, sky-gliding and horseback riding are some of the other attractions to Rosarito. In addition to the nearly 500 shops for the acquisition of souvenirs of truly one-of-a-kind special remembrances of Rosarito, we can also find hand crafts market with more that 150 different shops, where you can find: sterling silver, leather goods, blankets and many other hand crafts from all over Mexico. 

 The fishing village of Puerto Nuevo (Newport), just 15 miles south of Rosarito proper, has become famous for its fresh lobster, fried and served with rice, beans and hand made flour tortillas. Rosarito’s restaurants, including those in Puerto Nuevo, number over 100 and offer everything from the Puerto Nuevo lobster previously mentioned, to the traditional Mexican, Chinese, Italian, French, Americn and Continental cuisine. This abundance of fine foods, promts the return of many visitors to Rosarito year after year.   Historical Sites in Rosarito:
