You might want to stop to consider what the town's Medieval residents had to put up with. This wheel well on the corner of Rataskaevu and Dunkri in the Old Town was once one of the main sources of water for the Tallinn. According to legend, some of the locals got it into their heads that an evil water spirit lived in the well and threatened to make all the town's wells run dry if it wasn't given regular animal sacrifices. To keep the spirit happy, some cattle and sheep carcasses were thrown down the well, but the main victims were stray cats, who were rounded up and tossed, sometimes live, down the shaft. This practice was so common that the locals started calling this watering hole 'Cat's Well.' In a sense, the sacrifices worked - the town's wells never ran dry. But the practice of throwing animals down the well didn't do much for the water quality, and the Cat's Well had fallen into disuse by the mid 19th century. Rest assured that nowadays Tallinn's water is much safer to drink, and the cats of Old Town no longer live in fear.

Church of Our Lady of Kazan (Kaasani Jumalaema Sündimise kirik)
Built in 1721, this small, cross-shaped Russian Orthodox church is the oldest wooden structure in Tallinn. Extensive repairs in the 19th century gave the building a Classicist facade and brought a Classicist feel to the interior. Plaques commemorate the casualties of the Napoleonic wars and the Russo-Japanese War.

Church of the Transfiguration of Our Lord (Issandamuutmise kirik)
Originally belonging to St. Michael's Convent of the Cistercian Order (located next door and now housing the Gustavus Adolphus School), the church was given to an Orthodox congregation in 1716. The church has retained its original form, save the addition of a Baroque spire in 1776 and exterior renovations in the early 1800s. The carved-wood iconostasis is one of the most impressive of its kind.

Kaarli Church (Kaarli Kirik)
Built in pseudo-Romanesque style on the site of a 17th-century wooden church, Kaarli is an excellent example of the use of one of Estonia's greatest resources - limestone. In all, construction took 20 years (1862 - 1882), but painter Johann Köler completed Estonia's largest mural here, Come to Me, in just ten days. The church is also home to Estonia's largest church organ
