OLL is a very colorful and interesting history. From the beginning of the "Arroyo de los Reyes", the origination of Echo Park Lake, the birth of the movie industry, oil wells, the move of the Dodgers to our backyard, a haven for musicians, poets, artists and writers and even an off-season vacation haunt of the legendary Babe Ruth! We intend to create a complete history time line on this page. We are working with several sources including Local Historical Societies, Historians, The Presentation Sisters' archives, the school and parish as well as the Archdiocese of Los Angeles archives to gather all information available.
