The ruins of Lichnice Castle are on the edge of the Iron Mountains in the municipality of Třemošnice. The castle was probably constructed as a royal base in the first half of the 13th century. It was first mentioned in 1261, when it was in possession of Smil of Ronow, who called himself 'Smil of Lichtenburg' and thereby created the 'von Lichtenburg' family.
The castle had a triangular floor plan with two residential towers. In the 14th century, alterations were made, and it was reacquired by the Bohemian Crown in 1410. It was conquered in 1421, during the Hussite Wars, and besieged unsuccessfully in 1428.
In 1490, the castle and estate of Lichtenburg were acquired by the Trčka of Lípa family, who rebuilt the castle in a late Gothic style.
The edifice lost its importance at the end of the 16th century, and the fortifications were dismantled. By 1700, it was already described as a ruin.

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.
