Orekhovo (Russian: Оре́хово), often pronounced only as Orekh, is a Russian word which means "nut". The city was established in 1917 when three villages (Orekhovo, Zuevo, and Nikolskoye) were merged, hence its name.[7] Population: 120,670 (2010 Census);[3] 122,248 (2002 Census);[8] 137,198 (1989 Soviet census).[9] The first known facts about what now is Orekhovo-Zuyevo date back to 1209. The place was mentioned in the Moscow Chronicles as the place called "Volochok" where the battle between Vladimir's prince Yury and Ryazan's prince Izyaslav took place. The name "Volochok" (or, as it was later called, "Zuyev Volochok") is derived from the Slavic word for "portage": a place where wooden ships were carried by land from one river to another. In this place in particular, the ships were usually moved by land between the Klyazma and Nerskaya Rivers. The villages Orekhovo and Zuyevo were mentioned in the chronicle several more times during the Middle Ages.
