Arbor of the Eolian harp in Pyatigorsk. It was built from 1830 to October 1831 by the project of Giuseppe Bernardazzi at the highest point of the Mikhailovsky spur of Mount Mashuk. The prototype was the pavilion - Temple of Aeolus by the English architect William Chambers, built in the Kew park near London. In the gazebo, an original musical instrument was installed - the aeolian harp widely distributed in Europe. The street aeolian harp consisted of a pair of simple aeolian harps enclosed in a round boardhouse with a special wing that turned the harps at a certain angle to the wind. Air jets penetrating through narrow slots in the hulls of the harps caused oscillations of vein strings of different thickness, which produce various overtones. The original harp stood until 1861. In the 1890s, on the dome of the summerhouse, a sounding eolian harp of a simplified design was installed in the summer. In 1972 on the dome of the arbor a unique electromechanical musical device was installed, controlled by the wind - the electronic eolova harp , which sounded for almost 20 years. In 2008, the gazebo installed audio equipment, which plays independently of the wind.
