Grand Serail, Administrative headquarters in Zuqaq al-Blat, Lebanon.

The Grand Serail stands on Serail Hill in Zuqaq al-Blat, a few blocks from the Lebanese Parliament. Its two tall floors follow the Ottoman "New Order" design, with an austere facade running over 80 metres and modelled on Istanbul's Selimiye Barracks. The French replaced the northern arched gate with a lobed-arch balcony in 1926.

The building was constructed in 1853 as an Ottoman military installation controlling the region during Ottoman rule. It was later repurposed as the Prime Minister's official residence following Lebanon's independence in the 20th century.

The building displays Ottoman architectural traditions in its design, particularly visible at the north entrance and in its fortified layout. It sits on Serail Hill alongside other monuments that give the location particular importance in the city.

The site is not freely accessible to the public and requires prior official permission due to security measures. Visitors should submit requests through official channels well in advance and maintain realistic expectations about gaining entry.

Standing next to the building is a clock tower from 1897 that continues to display the time for the neighborhood today. This Hamidiyyeh Tower remains one of the city's oldest still-functioning timekeeping structures.
