At the very tip of the spit, there stands a monument dedicated to the millennial anniversary of Yaroslavl. Few Russian cities boast such a venerable age. Yaroslavl is the largest city on the Golden Ring. Furthermore, Yaroslavl was the first Russian city to be sited on the Volga.

What about Kazan, you ask, that was founded five years before Yaroslavl! Yes, but it became part of Russia only under Ivan the Terrible in the midth century, and so does not qualify as a city of Old Rus. The man in whose honor the city is named deserves a special mention. Yaroslav was the son of Prince Vladimir, who baptized Rus.

Under Yaroslav, many churches were built and society and culture blossomed. He drafted the first legal code in Russia, and established relations with Byzantium and many European states as well.

His biography reads like that of a high-flying top manager. Later, his father granted Yaroslav the title of prince of the Novgorod lands, which were far richer — ancient Novgorod was a large trading city, and even part of the Hanseatic League.

After a long struggle with his brother, Yaroslav became the prince of Kiev, and hence the main ruler in all of Rus. There in Kiev, he built the famous St. Sophia Cathedral, and also liberated the country from the marauding Pechenegs, a semi-nomadic people of Turkic origin. Incidentally, Yaroslav was married to the daughter of the Swedish king, and his own daughter, Anna Yaroslavnamarried Henry I and became queen of France!

As in any old Russian city, Yaroslavl contains a huge number of churches and several monasteries. You can try to visit all of them, of course, but be warned that even enthusiasts risk culture fatigue. The one place you definitely need to visit in Yaroslavl is the museum reserve.

This high-walled fortress on a steep bank of the river may look like a kremlin, but no, it is the former Transfiguration Monastery of 13th-century vintage.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
