The Church of the Holy Trinity, since February 2008 Holy Trinity Cathedral, was built around 1400. The Žilina castle is assumed to be already there as early as the 13th century, of which there are documents from 1318 to 1454. It was originally consecrated to Mary, but in the 16th century it was reconsecrated as the Church of the Holy Trinity. The chapel of John of Nepomuk was added in 1762. The church burned down three times, in 1678, 1848 and partly in 1886. The three naves of the church were originally in Gothic style, but after a reconstruction it was styled to Renaissance style. The last major reconstruction of the church was done in 1942.
The main altarpiece in the main altar depicts the Holy Trinity, the side altars depict Immaculate Conception and the Crucifix, and near the entrance there is a picture of Saint Anne. In the compounds of the church stands separate Burian's Tower, built in the first half of the 16th century. The tower offers a good view of the preserved medieval part of the town.

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.
