The roots of Saulkrasti Secondary School reach back to Pabaži, to 1912, when a young teacher – Olga Veicmane (after marriage: Cīrule) arrived from Riga to teach the sea captain Reisons’ daughter. Soon many other tutor-seekers joined her and in autumn of 1912 a school was established in Pabaži. The school had a good reputation, and pupils came from the entire surrounding area. In January of 1913, the school was moved to more spacious premises at 20 Rīgas Street. 
During World War I the school was ruined and its furniture and equipment were dragged away. In 1918 the school was reopened, giving an opportunity for children to enjoy many interesting and captivating activities such as choir singing, theatre group and a group of new writers. The headmaster of the school Olga Cīrule became the soul of local social life. By 1933, the number of pupils had outgrown the size of the school. Therefore in 1933, the school was moved to 3 Raiņa Street – to the premises of the former outpatient clinic. The school was named Pēterupe Primary School. In 1950, the school became Saulkrasti Secondary School and at the end of 1956 the school obtained a new and beautiful building at 6 Smilšu Street.
