De Wallen or De Walletjes  is the largest and best known red-light district in Amsterdam and a major tourist attraction. It is located in the heart of the oldest part of the city (Amsterdam-Centrum), covering several blocks south of the church Oude Kerk and crossed by several canals. De Wallen consists of a network of alleys containing approximately three hundred tiny one-room cabins rented by prostitutes who offer their sexual services from behind a window or glass door, typically illuminated with red lights. The area also has a number of sex shops, sex theatres, peep shows, a sex museum, a cannabis museum, and a number of coffee shops that sell marijuana. 26 coffeeshops in the De Wallen area will have to close their doors between 1 September 2012 and 31 August 2015.[1] As part of new restrictions which came into force in 2012, a Dutch judge ruled tourists can now legally be banned from entering cannabis cafes

The UNESCO World Heritage Site known as the Defence Line of Amsterdam (in Dutch named Stelling van Amsterdam) is a 135 km long ring of fortifications around Amsterdam, consisting of 42 forts located between 10 to 15 kilometers the centre, and lowlands that can easily be flooded in time of war. The flooding was designed to give a depth of about 30 cm, insufficient for boats to traverse. Any buildings within 1 km of the line had to be made of wood, so that they could be burnt and the obstruction removed.

A study done by Rijkswaterstaat in 1937 showed that the sea defenses in the southwest river delta were inadequate to withstand a major storm surge. The proposed solution was to dam all the river mouths and sea inlets thereby shortening the coast. However because of the scale of this project and the intervention of the Second World War its construction was delayed and the first works were only completed in 1950. The North Sea flood of 1953 gave a major impulse to speed up the project. In the following years a number of dams were built to close off the estuary-mouths. In 1976, under pressures from environmental groups and the fishing industry, it was decided not to close off the Oosterschelde estuary by a solid dam but instead to build the Oosterscheldekering, a storm surge barrier which is only closed during storms. It is the most well-known (and most expensive) dam of the project. A second major hurdle for the works was in the Rijnmond area. A storm surge through the Nieuwe Waterweg would threaten about 1.5 million people around Rotterdam. However, closing off this river mouth would be very detrimental for the Dutch economy, as the Port of Rotterdam - one of the biggest sea ports in the world - uses this river mouth. Eventually, the Maeslantkering was built in 1997, keeping economical factors in mind: the Maeslantkering is a set of two swinging doors that can shut off the river mouth when necessary, but which are usually open. The Maeslantkering is forecast to close about once per decade. Up until now (January 2012), it has closed only 1 time, in 2007. The project was finished with the construction of the Maeslantkering in 1997.

The Dom Tower (Cathedral Tower, Dutch: Domtoren) of Utrecht is the tallest church tower in the Netherlands,[1] at 112.5 metres (368 feet) in height, and the Gothic-style tower is the symbol of the city. The tower was part of the Cathedral of Saint Martin, Utrecht, also known as Dom Church, and was built between 1321 and 1382, to a design by John of Hainaut. The cathedral was never fully completed due to lack of money. Since the unfinished nave collapsed in 1674 the Dom tower became a free standing tower.

Dutch is a Germanic language spoken by about 27 million people world-wide. Most people living in the Netherlands and Flanders (the northern part of Belgium) use it as a first language, while in Suriname, Aruba and the Netherlands Antilles it is widely used as a second language. Historically, French Flanders and parts of the Lower Rhine Region in Germany also belong to the Dutch language sphere, and during the age of colonization it has also spread to Indonesia and other former Dutch colonies. Dutch is the ancestor of the Afrikaans language spoken in South Africa and Namibia, which is mutually intelligible to Dutch. Lastly, it is closely related with other West Germanic languages, such as German (especially the Low German dialects), English and West Frisian.

The Dutch Golden Age,  was a period in Dutch history, roughly spanning the 17th century, in which Dutch trade, science, military, and art were among the most acclaimed in the world. The first half is characterized by the Eighty Years' War till 1648. The Golden Age went on in peace time during the Dutch Republic until the end of the centuryIn 1568, the Seven Provinces that later signed the Union of Utrecht (Dutch: Unie van Utrecht) started a rebellion against Philip II of Spain that led to the Eighty Years' War. Before the Low Countries could be completely reconquered, a war between England and Spain (the Anglo-Spanish War (1585–1604)) broke out, forcing Spanish troops to halt their advances and leaving them in control of the important trading cities of Bruges and Ghent, but without control of Antwerp, which was then arguably the most important port in the world. After a siege, on August 17, 1585 Antwerp fell, and the division of the Northern and Southern Netherlands (mostly modern Belgium) was defined. The United Provinces (roughly today's Netherlands) fought on until the Twelve Years' Truce, which did not end the hostilities. The Peace of Westphalia in 1648, which ended the Thirty Years' War, brought the Dutch Republic formal recognition and independence from the Spanish crown.

The Dutch Water Line (Dutch: Hollandsche Waterlinie) was a series of water based defences conceived by Maurice of Nassau in the early 17th century, and realised by his half brother Frederick Henry. Combined with natural bodies of water, it could be used to transform the economic heartland of the Dutch Republic almost into an island.
