Dolbadarn Castle is a fortification built by the Welsh prince Llywelyn the Great during the early 13th century, at the base of the Llanberis Pass, in northern Wales. The castle was important both militarily and as a symbol of Llywelyn's power and authority. The castle features a large stone keep, which historian Richard Avent considers the finest surviving example of a Welsh round tower. In 1284 Dolbadarn was taken by Edward I, who removed some of its timbers to build his new castle at Caernarfon.
The remaining parts of the castle continued to be used as a manor house into the 14th century. By the 18th century, however, Dolbadarn Castle was ruined and uninhabited. From the 1760s onwards, however, it became a popular topic for painters interested in the then fashionable landscape styles of the Sublime and the Picturesque. J. M. W. Turner's 1800 work Dolbadarn Castle depicted the back-lit castle looming over the landscape and became particularly famous, but the paintings of the castle by Richard Wilson and Paul Sandby also represent important artistic works of the period.

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.
