Cádiz is known worldwide for its watchtowers. They are witness to the trade and prosperity which the city experienced in the 18th century. At this time, the Tavira Tower the official watchtower of Cádiz due to the fact that it is situated in the centre of town, and was also the highest point in the town at 45 meters above the sea level.
Don Antonio Tavira was the first watchman of the tower and used his telescope to see the ships full with goods coming from America. Today the Camera Obscura enables us to observe Cádiz and its development in the 21th century.

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.
