Sa'adat School belongs to Qajar Era and it is located in Imam Khomeini Street, Bushehr. With a new educational method, this school was founded in 1900. Historically, Sa'adat School is the mother of schools on the south of Iran. Similar to the central texture of Bushehr, the texture of this school is very beautiful. This school was founded by Ahmad Khan Darya Beygi, the governor of Bushehr, Persian Gulf ports and Omanis at that time, to the request of Ahmad Khan Darya Beygi due to the cash assistance of Mozaffar ad-Din Shah Qajar and therefore, it was known as Sa'adat Mozaffari School. Ahmad Khan Darya Beygi suffered a lot of work when establishing and founding this school. Currently, the anniversary of establishment of Sa'adat School is celebrated as the Day of Bushehr. This school has been registered as a national monument of Iran.
