The Kaarli Church (or Charles XI’s Church) was built between 1862-1882 to replace the original Kaarli Church, itself founded in 1670 on the order of Sweden's King Charles XI. Like many wooden structures located outside the city wall, the first Kaarli Church burned down during the Great Northern War in the early 1700s.
Architect Otto Pius Hippius from St. Petersburg built the present limestone church using a special arch technique that gave it have a vast, open interior. With its wonderful acoustics and seating capacity of 1,500, the church is often used as a venue for choral concerts.
The Kaarli Church is home to the first Estonian fresco, “Come to Me,” painted in 1879 by famed Tallinn artist Johann Köler. It also boasts the country's largest church organ, installed in 1924.

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.
