Koza Han

Koza Han is a historic caravanserai in the center of Bursa, Turkey, known for its long association with the silk trade. Its Turkish name means “inn of the silk cocoon,” reflecting the building’s historical role in the production, exchange, and sale of silk cocoons and silk textiles. The han stands beside the Orhan Gazi Mosque in Bursa’s historic commercial district, an area that developed into an important economic center during the Ottoman period. Bursa served as the first capital of the Ottoman Empire and became one of the empire’s principal centers of silk production and international commerce. From the fourteenth through the sixteenth centuries, the city center accumulated hans, covered bazaars, a bedesten, mosques, and other commercial institutions. These buildings supported merchants moving goods across Ottoman trade routes and provided accommodation, storage, workshop space, and offices. Koza Han became one of the largest and most significant examples of this urban-commercial architecture. Sultan Bayezid II ordered the construction of Koza Han in February or March 1490. The architect was Abdul Ula Bin Pulad Shah, and the building opened in September 1491. It operated through the Ottoman waqf system, with its revenues assigned to the maintenance of Bayezid II’s mosque complex in Istanbul. The han therefore functioned not only as a marketplace and lodging facility but also as part of a religious and charitable endowment structure. The building continued to accommodate silk-related commerce for centuries. In the early sixteenth century, the commercial representative of the Medici family of Florence maintained an office there, illustrating Bursa’s connections with European merchants. Although silk production and cocoon trading are no longer as dominant as they were historically, shops selling silk goods remain an important part of the site’s identity. The complex also contains cafés and tea gardens, making it both a heritage destination and an active urban gathering place. Architecturally, Koza Han has a rectangular plan organized around a large central courtyard measuring approximately 45.9 by 37.5 meters. Two-story arcaded galleries surround the courtyard and provide access to small vaulted rooms. There are 50 rooms on the ground floor and 54 on the upper floor. A distinctive octagonal prayer room stands above the center of the courtyard on eight pillars. Its elevated position helped protect the space from animals kept at ground level by visiting merchants. A fountain and ablution area are located beneath it. The exterior uses alternating courses of brick and stone, producing a characteristic striped visual effect. The monumental entrance projects from the façade and features a decorated portal with spiral molding, geometric motifs, and colored tile set into the spandrels above the arch. The building has undergone repeated repairs and restorations, including documented work in 1630, 1671, and 1784. The central mosque was restored in 1946 and again in 2007. Today, Koza Han is preserved as a historic commercial and cultural site in Bursa. Its silk shops, courtyard, cafés, tea gardens, and Ottoman architecture connect contemporary visitors with the city’s role in regional and international trade. Queen Elizabeth II visited the han with Turkish President Abdullah Gül in 2008, adding to its international visibility.

Koza Han emerged during Bursa’s period as the first capital of the Ottoman Empire and as a major center of silk production and long-distance commerce. The city’s central market area developed through the construction of hans, covered bazaars, a bedesten, mosques, and related commercial buildings. These facilities formed an interconnected economic district where merchants could lodge, store goods, arrange transactions, and employ craftsmen. Sultan Bayezid II commissioned Koza Han in February or March 1490. The architect was Abdul Ula Bin Pulad Shah, and the complex opened in September 1491. Its income was placed within the Ottoman waqf system and assigned to the upkeep of Bayezid II’s mosque complex in Istanbul. This arrangement linked the commercial activity of the Bursa han to the financing of a major imperial religious foundation. The building’s name refers to silk cocoons, a commodity central to Bursa’s economy. Koza Han served merchants involved in the handling and sale of cocoons and silk textiles, while also providing rooms for trade, storage, and accommodation. Its importance extended beyond local commerce: in the early sixteenth century, the Medici family’s commercial agent operated from the building, demonstrating its role in international trade networks. Koza Han was repeatedly repaired during the Ottoman and later periods. Major documented interventions took place in 1630, 1671, and 1784. The central prayer room was restored in 1946 and again in 2007. These works helped preserve the building’s courtyard-centered plan, masonry façades, vaulted rooms, entrance portal, and elevated mosque. The complex is organized around a courtyard measuring approximately 45.9 by 37.5 meters. A two-story gallery surrounds the open space, with 50 rooms on the ground floor and 54 on the upper floor. At the center is an octagonal stone mescit carried on eight pillars. A marble staircase leads to the prayer room, while a fountain and ritual-washing area occupy the space below. The elevated design separated the mosque from pack animals that merchants kept on the ground floor. Its exterior combines alternating brick and stone courses. The projecting entrance portal is ornamented with spiral edging and geometric tile decoration above the arch. These features, together with the courtyard, vaulted rooms, and central prayer structure, make Koza Han a notable example of Ottoman commercial architecture. Silk remains visible in the building’s contemporary identity, although the large-scale silk economy that once sustained Bursa is no longer as prominent. Today the han contains silk shops, cafés, and tea gardens and functions as both an active urban space and a heritage attraction. Its international profile was reinforced by Queen Elizabeth II’s 2008 visit with Turkish President Abdullah Gül.
