Worshippers praying at Sheikh Abu Bakr Mosque.

Saudi Arabia has reopened a 300-year-old mosque after its renovation as part of Prince Muhammad Bin Salman's project to preserve historical mosques in the Kingdom.

Worshippers returned to Sheikh Abu Bakr Mosque in Al Ahsa Governorate of the Eastern Province of the Kingdom to perform prayers, the Saudi Press Agency (SPA) reported on Thursday.

Abu Bakr Mosque is one of the oldest heritage buildings in the middle of the old Al Kut neighbourhood in Al Hofuf, Al Ahsa. Distinguished by its construction in a unique architectural style, the mosque was built of mud, pebbles and logs of palm wood.

The mosque's capacity was increased to accommodate 166 worshippers.

Before its reconstruction, the area of the mosque was about 565 square metres, accommodating some 125 worshippers. Following the rehabilitation and reconstruction work, the mosque's capacity increased to accommodate 166 worshippers.

The history of the mosque goes back to more than 300 years, as Sheikh Ahmed Abu Ali sponsored its foundation. The mosque included a religious school, which was considered a beacon for Islamic religious teachings, as many students from the Gulf countries, India and Pakistan flocked to it at the time.

Many Imams belonging to the Abu Bakr family took turns to lead the mosque, including Sheikh Bin Muhammad Omar Al Mulla, known as Abu Bakr Al Kabeer, Sheikh Abdullah Al Mulla, known as Abu Bakr Al Sagheer, and Sheikh Ahmed Abu Bakr Al Mulla, who was followed by his sons.
