The people of the Netherlands established a trading settlement at a fine natural harbour on the Caribbean island of Curaçao in 1634. The town developed continuously over the following centuries. The modern town consists of several distinct historic districts whose architecture reflects not only European urban-planning concepts but also styles from the Netherlands and from the Spanish and Portuguese colonial towns with which Willemstad engaged in trade.

Historic Area of Willemstad, Inner City and Harbour, Curaçao

The Historic Area of Willemstad is an example of a colonial trading and administrative settlement. It was established by the Dutch on the island of Curaçao, situated in the southern Caribbean, near the tip of South America. Starting with the construction of Fort Amsterdam in 1634 on the eastern bank of Sint Anna Bay, the town developed continuously over the following centuries.

The modern town, the capital of the island nation of Curaçao, consists of several distinct historic districts, reflecting different eras of colonial town planning and development. Punda, the oldest part of the city, was built in the 17th century on the eastern side of Sint Anna Bay, adjacent to Fort Amsterdam and is the only part of the city that had a defence system consisting of walls and ramparts. The other three historic urban districts (Pietermaai, Otrobanda and Scharloo) date from the 18th century. Water Fort and Rif Fort, also included in the inscribed property, were built in the late 1820s as part of a more extensive series of fortifications. In the midst of the historic area is a natural deep-water harbour. The entire property encompasses 86 ha and is surrounded by a 87 ha buffer zone.

The architecture of Willemstad has been influenced not only by Dutch colonial concepts but also by the tropical climate and architectural styles from towns throughout the Caribbean region, with which the settlement engaged in trade. Early residences constructed in Punda followed Dutch urban design. In the 18th century, local materials and craftsmanship as well as new architectural elements, such as galleries, began to appear. As the city expanded beyond Punda, the architectural style of the residences evolved. For example, the development of Otrobanda was not restricted by ramparts and houses were built on spacious lots and resembled plantation houses surrounded by galleries. Moreover, the social and cultural differences from Afro-American, Iberian and Caribbean inhabitants have contributed to enriching the building traditions as well as the city’s cultural life. The result is a European architectural style with regional adaptations in a rich array of Caribbean colours. The colourful buildings of Willemstad are a local tradition dating from 1817, when the previous style of white lime finish on a building exterior was prohibited, apparently to protect eyesight from the glare. Predominant colours are red, blue, yellow ochre and various shades of green.

Willemstad is an exceptionally well preserved example of a Dutch colonial trading settlement. Due to the interchange of cultures, it shares a common cultural history with other counterpart cities in the Caribbean region, which is a very particular aspect of the property. The unique setting in a natural harbour qualifies the Historic Area of Willemstad as a rare example of a historic port town laid out in a setting of natural waters.

Seventeenth-Century Canal Ring Area of Amsterdam

Seventeenth-Century Canal Ring Area of Amsterdam inside the Singelgracht

The historic urban ensemble of the canal district of Amsterdam was a project for a new ‘port city’ built at the end of the 16th and beginning of the 17th centuries. It comprises a network of canals to the west and south of the historic old town and the medieval port that encircled the old town and was accompanied by the repositioning inland of the city’s fortified boundaries, the Singelgracht. This was a long-term programme that involved extending the city by draining the swampland, using a system of canals in concentric arcs and filling in the intermediate spaces. These spaces allowed the development of a homogeneous urban ensemble including gabled houses and numerous monuments. This urban extension was the largest and most homogeneous of its time. It was a model of large-scale town planning, and served as a reference throughout the world until the 19th century.

Brief synthesis

The Amsterdam Canal District illustrates exemplary hydraulic and urban planning on a large scale through the entirely artificial creation of a large-scale port city. The gabled facades are characteristic of this middle-class environment, and the dwellings bear witness both to the city’s enrichment through maritime trade and the development of a humanist and tolerant culture linked to the Calvinist Reformation. In the 17th and 18th centuries, Amsterdam was seen as the realization of the ideal city that was used as a reference urban model for numerous projects for new cities around the world.

Criterion (i): The Amsterdam Canal District is the design at the end of the 16th century and the construction in the 17th century of a new and entirely artificial ‘port city.’ It is a masterpiece of hydraulic engineering, town planning, and a rational programme of construction and bourgeois architecture. It is a unique and innovative, large-scale but homogeneous urban ensemble.

Criterion (ii): The Amsterdam Canal District bears witness to an exchange of considerable influences over almost two centuries, in terms not only of civil engineering, town planning, and architecture, but also of a series of technical, maritime, and cultural fields. In the 17th century Amsterdam was a crucial centre for international commercial trade and intellectual exchange, for the formation and the dissemination of humanist thought; it was the capital of the world-economy in its day.

Criterion (iv): The Amsterdam Canal District represents an outstanding example of a built urban ensemble that required and illustrates expertise in hydraulics, civil engineering, town planning, construction and architectural knowhow. In the 17th century, it established the model for the entirely artificial ‘port city’ as well as the type of Dutch single dwelling with its variety of façades and gables. The city is testimony, at the highest level, to a significant period in the history of the modern world.
