The Beylerbeyi Palace offers a glorious blend of traditional Ottoman architecture with neoclassical, baroque, and Renaissance influences. There are six halls and 24 rooms. The palace's floors are covered with special carpets imported from Egypt and filled with furniture adorned with huge crystal chandeliers. One of the most striking features of the palace is the magnificent decorations on the ceilings. Sultan Abdulaziz's interest in painting directly contributed to the development of these decorations. Painters and calligraphers brought from Europe brought the elegant details of the palace to life.
The palace consists of two main parts: Mabeyn-i Humayun and Valide Sultan Apartment. Mabeyn-i Humayun is defined by a central hall where the formal occasions of the palace are carried out. Valide Sultan's Apartment is one of the most eye-catching parts of the palace. This area was designed to provide the highest level of comfort in the palace and was used as the living space of the Valide Sultan. The harem section was built separately from the main building but has not survived to the present day. It contained the private living spaces of ladies and gentlemen.The Beylerbeyi Palace is also an important building with its landscaping use. Its garden and its extending sets are also quite magnificent. Apart from the garden right in front of the palace, there are 4 garden sets and a grove behind the sets. The most delightful gardens of Istanbul are located just outside the Beylerbeyi Palace. The upper parts of these gardens have been transformed into areas where visitors can enjoy their time.
Other palace structures are located within the land. The Deniz Pavilion stands out among these structures. There are two Deniz Pavilions in the palace complex, in the Harem and Mabeyn sections. As their name suggests, they are very close to the Bosphorus and their roofs look like tents, so they are also known as Cadir Pavilion (cadir means tent). The Deniz Pavilion in the Harem section is reserved for Valide Sultan.
The Marble Pavilion hosts a mosque with lakes and fountains. This mosque was built for the hunting purposes of Sultan Mahmud II. The Yellow Pavilion is close to the Marble Pavilion and is designed for relaxation. It takes its name from its light yellow exterior and its ceiling is decorated with ornaments. Since they are all close to the shores of Beykoz, the palace, and these structures look even more impressive than a ferry crossing the Bosphorus.
Has Ahir Mansion is a mansion that reflects the horse culture of the Ottoman period. There are horses and other animal figures on the ceilings in the entrance area. There are also horse-themed reliefs on the chandelier and other elements.
