Brahehus Castle was built by Per Brahe between 1637 and 1650s. Soon after Per Brahe died in 1680 Brahehus was abandoned and moved as a Crown property in the Great Reduction under Charles XI of Sweden. In 1708 the castle was destroyed by fire and not rebuilt anymore. From the ruins you have a fantastic view of lakes Vättern and Visingsö.
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.
