A pearl of architecture

St. Nicholas Cathedral in Kyiv is a wonderful masterpiece of Ukrainian architecture of the 20th century. It was created in the Gothic style by the famous architect Horodetskiy in 1909. Despite reinforced concrete that was used for this building, the Cathedral strikes observers with its lighness, harmony and perfection.
Tracery spires of 64 meters in height impetuously rise impressively in the sky. The central portal is decorated with a big round stained-glass window in the shape of Cothic rose. Another two portals are ornamented with bas-reliefs with religious topics.
The Communist authorities did not value the beauty of this Cathedral and used it as a storehouse and archives since 1936. In 1978 it was decided to transform it into a concert hall. In 1980 the Cathedral opened its doors for lovers of classic music, especialy organ pieces one.
A Czech company created an organ for that hall, styling it specifically for the interior of the Cathedral. Though the concert hall is not big and the stage is poorly seen from most of seats, but Gothic interior and peerless acoustics give to audience imcomparable aesthetic enjoyment.
In St. Nicholas Cathedral you can hear a music of Bach, Handel, Mozart, Haydn, Vivaldi, Verdy and many others, perfomed by Ukrainian and foreigh musicians and singers.

[Very good work.  Most of my changes were subtle nuances in meaning, rather than large mistakes.]
