The border area is mostly plain, with few mountains. An important natural landmark is Lake Khasan, which was the location of the Battle of Lake Khasan. Other landmarks include Zaozyornaya Hill (Russian: сопка Заозёрная), and Gora Priozernaya (Russian: Гора Приозерная). On the Russian side stands a building called "Korean-Russian House of Friendship" (Russian: Дом корейско-российской дружбы). Furugelm Island, the southernmost point in Asian Russia, is located close to the maritime border.
