Teylers Museum Haarlem dates from 1784 and is located directly on the Spaarne river, is the oldest museum in the Netherlands.
A very wealthy cloth and silk manufacturer, Pieter Teyler van der Hulst (1702-1778), founded the Teylers Museum. He was inspired by the Enlightenment and he had included in his will that his collection and assets should be used to promote art and science.
The interior of the museum, with the monumental Oval Hall as its showpiece, is very worth seeing.
The result is this beautiful museum, with textbooks, drawings, fossils, physical instruments and minerals. Seems boring but it is a beautiful and fascinating museum.
Also on display is a famous collection of drawings by Rembrandt, Michelangelo, Rafael, historical physical instruments and 19th and 20th century paintings.
