The Novgorod Kremlin, also known as Detinets, stands as a prominent historical fortress in the heart of Veliky Novgorod, Russia. Founded as early as the 10th century, the Kremlin's current stone walls and towers were erected in the 14th and 15th centuries to protect the city from military threats. This architectural marvel is regarded as one of the oldest fortifications in Russia and is a prime example of medieval military architecture. Notable structures within the Kremlin include the Millennium of Russia monument, which commemorates the 1000th anniversary of Russia's founding, and the Saint Sophia Cathedral, one of Russia's oldest churches, showcasing stunning Byzantine architecture. The Kremlin has played a vital role in the history of Novgorod as a political, religious, and cultural center, and it now serves as a museum and a public space where visitors can explore its rich history and enjoy panoramic views of the Volkhov River.
