The National Museum of Wales was founded in 1905, with its royal charter granted in 1907. Construction of a new building in the civic complex of Cathays Park began in 1912, but owing to the First World War it did not open to the public until 1922, with the official opening taking place in 1927. The museum has collections of botany, fine and applied art, geology, and zoology.
The National Museum of Art opened in 2011. The collection of Old Master paintings in Cardiff includes, among other notable works, The Virgin and Child between Saint Helena and St Francis by Amico Aspertini, The Poulterer's Shop by Frans Snyders, A Calm by Jan van de Cappelle Since 2016, the museum has had Rembrandt's 1657 Portrait of Catharina Hooghsaet on permanent display.
There are also collections of landscape paintings, portraits, French art and works by all of the notable Welsh artists, including landscapes by Richard Wilson and the pioneering Thomas Jones. The collection of 20th-century art includes works by sculptors Jacob Epstein, Herbert Ward and Eric Gill and painters including Stanley Spencer, the British Impressionist Wynford Dewhurst, L. S. Lowry, and Oskar Kokoschka.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
