The Royal Coin Cabinet is a museum dedicated to the history of money. The museum includes exhibitions of coins, banknotes (the first in the world was issued in 1661 by Stockholms Banco), treasure hoards and piggy banks. Particularly notable are the oldest Swedish coin, a copper plate coin dating from Queen Christina's reign in 1644 that is thought at 19.7 kg to be the heaviest in the world, some of the Lohe treasure found in 1937 on Gamla Stan, Weimar Republic inflation currency and some Nobel prize medals.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
