On the west bank of the Volkhov River, and surrounded by a pleasant wooded park, the kremlin is one of Russia’s oldest. Originally called the Detinets (and still often referred to as such), the fortification dates to the 9th century, and was rebuilt with brick in the 14th century; this still stands today. The complex is worth seeing with a guide; arrange one through the tourist office. You can walk part of the kremlin walls for views over the complex and the city.
Boat tours operate from the kremlin's pier.
