Novgorod is one of the ancient cities in Russian Federation. There is a great number of monuments, museums and other places of interest on the territory of Novgorod. Novgorod was founded in 859 AD on the Volkhov River not far from the Ilmen Lake. It is considered that the history of Russian statehood has begun from this place. The city history is closely connected with the main periods of development and life of Russia. In 862 this city became the first capital of Rus but later the capital was moved to Kiev by Vladimir the Great. In those days Novgorod was playing a key role in expanding of culture and literacy in Russia. Almost all citizens of the city were educated. Novgorod was not only a cultural center but it was also a reliable fortress protecting Russian borders. During Tatar and Mongol invasion Novgorod didn’t suffer thereby it kept its unique ancient Russian architecture which is now attracting tourists from all over the world.
They also have traditions such as culinary. We learn about the peculiarities of the historical Novgorod cuisine from epics and chronicles.
On the tables of the Novgorodians were such dishes as "flint" (thick soup made from fish fin meat), elk lips, white lynx meat, fried swans and boiled bear paws.
Novgorod cuisine was distinguished by an abundance of fish dishes. Back in the 18th century, whitefish, Baltic taimen and even sturgeon were caught in Lake Ilmen!
“Ilmen style pike perch” is still one of the favorite dishes of Novgorodians and guests of the city.
