The Kaiser Wilhelm Pavilion is a historic structure located in Hereke, Körfez district of Kocaeli, Türkiye, along the coast of the Marmara Sea. It was built in 1898 for the visit of German Emperor Wilhelm II. Constructed by order of Ottoman Sultan Abdülhamid II, the pavilion hosted diplomatic interactions of the period while standing out for its architectural and craftsmanship qualities. Its name honors the German emperor commemorating this diplomatic visit.

Construction Process and Architectural Features
The pavilion was completed in approximately three weeks in the carpentry workshops of Yıldız Palace prior to the 1898 visit. Built entirely of wood, it was assembled using a nail-free technique similar to shipbuilding methods. Components were transported by sea to Hereke and assembled within a single day. This represents a significant example of portable and rapid construction techniques of the era.
While the architect’s identity is not definitively known, sources frequently mention Raimondo d’Aronco. The pavilion was positioned for easy access both from land and sea. Its exterior is symmetrical, featuring a slightly sloped central roof flanked by symmetrical domes on either side, creating visual balance and architectural harmony.
Interior Layout
The pavilion comprises an entrance hall, a large salon, and several smaller rooms. Internal transitions are facilitated by double-leaf doors. Walls and ceilings are adorned with gold leaf and kalem işi (Ottoman-style ornamental painting). The flooring includes Hereke carpets produced by the Hereke Carpet and Textile Factory, silk upholstery fabrics, and drapes. The salon emphasizes red and green tones. Most furniture pieces are original items from the palace, including a tile-embellished stove, a piano, rosewood tables, and early 20th-century seating sets.

Historical Visit and Diplomatic Context
German Emperor Wilhelm II and Empress Augusta Victoria visited the Ottoman Empire in 1898, traveling from Haydarpaşa to Hereke by special train. During their stay, carpets, silk fabrics, and decorative textiles produced at the Hereke Factory were presented to the German delegation. In return, Wilhelm II gifted Sultan Abdülhamid II a rare insect collection containing silkworm pests.
The Empress also presented gold pins to three young girls working on the factory looms (Münevver, Binnaz, and Emine). The emperor walked on carpets laid from the train station to the pavilion, and the ceremony was conducted in a grand protocol. The visit lasted approximately six hours before the imperial party returned to Istanbul by sea. Ottoman officials including Müşir Şakir Pasha, Foreign Minister Tevfik Pasha, the Berlin Ambassador, aides, and protocol officers were present.
Hereke Industry
At the time, Hereke was a significant industrial hub within Ottoman modernization efforts. The Hereke Imperial Factory, founded in 1843, initially produced palace upholstery by 1845 and later expanded into carpet production in the 1870s, earning international awards. Therefore, the pavilion functioned not only as a resting place but also as a symbol of Ottoman-German diplomacy, a showcase of Hereke industry, and a convergence of state architecture and art.
