The Rijksmuseum is a Dutch national museum dedicated to arts and history in Amsterdam. The museum has on display 8,000 objects of art and history, from their total collection of 1 million objects from the years 1200–2000. The collection contains more than 2,000 paintings from the Dutch Golden Age by notable painters such as Jacob Isaakszoon van Ruisdael, Frans Hals, Johannes Vermeer, Jan Steen, Rembrandt, and Rembrandt's pupils. Probably the most well known pieces of art are The Milkmaid (c. 1658) painted by Johannes Vermeer and The Night Watch (1642) by Rembrandt.
The Rijksmuseum was founded in The Hague in 1800 and moved to Amsterdam in 1808, where it was first located in the Royal Palace and later in the Trippenhuis. The current main building was designed by Pierre Cuypers and first opened its doors in 1885. On 13 April 2013, after a ten-year renovation which cost € 375 million, the main building was reopened by Queen Beatrix. In 2013, it was the most visited museum in the Netherlands with a record number of 2.2 million visitors.
The museum has taken the unusual step of making some 125,000 high-resolution images available for download via its Rijks Studio software, with plans to add another 40,000 images per year until the entire collection of one million works is available, according to Taco Dibbits, director of collections.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
