The northernmost of the three Kremlin towers on Red Square is the 70-meter-high Nikolausturm ( Никольская башня ), named after St. Nicholas of Myra , whose icon originally adorned the lower part of the tower. This tower is one of the four towers of the Moscow Kremlin today that have an entrance gate to the Kremlin. It was originally built in 1491 to a design by the master builder Pietro Antonio Solari , who as one of several Italian architects who were active in Moscow at the time, played a key role in the construction of the Kremlin ensemble. In 1806 the tower was significantly redesigned and was given a Gothic one - completely unusual for the Kremlin buildingsTop. Only a few years later it was destroyed by the French troops in the war against Napoleon and was finally rebuilt in 1816 with the participation of Joseph Bové . With its Gothic style, the Nikolaus Tower is still the most unusual of the total of 20 Kremlin towers.
