Fodor's Expert Review Teylers Museum

Just north of the Waag (the Weigh House, built entirely of stone in 1598 and now a pleasant little café), Teylers is housed in a grand 18th-century building with mosaic floors. The best sort of small museum, it is based on the whims of an eccentric private collector, in this case the 18th-century merchant Pieter Teyler van der Hulst. It's the country's oldest museum, founded in 1784, and has a mixture of exhibits: fossils and minerals sit alongside antique scientific instruments, such as a battery of 25 Leiden jars, dating to 1789 and used to store an electric charge. The major artistic attraction is a legendary collection of drawings and prints by Michelangelo, Rembrandt, Raphael, and other Old Masters that once belonged to Queen Christina of Sweden.
