Museums include the Turkmen Fine Arts Museum and Turkmen Carpet Museum, noted for their impressive collection of woven carpets as well as a Turkmen history museum and the Ashgabat National Museum of History, which displays artifacts dating back to the Parthian and Persian civilizations. Ashgabat was also home to the Arch of Neutrality, a 75 m (250 ft) tall tripod crowned by a golden statue of late president Saparmurat Niyazov (also known as ''Turkmenbashy'', or head Turkmen). The 15 m (50 ft) high statue, which rotated in order to always face the sun during daylight hours, was removed on August 26, 2010, after Niyazov's successor, current President Berdimuhamedov, made clear earlier in the year that the statue was to be taken out of Ashgabat's Independence Square. In 2011 a Monument to the Constitution was built, its total height of 185 m (607 ft) makes it the second tallest structure in Turkmenistan.
