The National Assembly Building is used by the Bulgarian parliament for parliamentary debates. The main building has been proclaimed a monument of culture for its historic significance. Situated in downtown Sofia, it was designed in Neo-Renaissance style by Konstantin Jovanovic, a Serbian-Bulgarian architect who received his education in Vienna and Switzerland and whose other works include the Parliament of Serbia building. It was constructed between 1884 and 1886 by Friederich Wilhelm Gustav Liebe, a young builder from Saxony who was only 22 years old when construction began.The building was originally painted in an off-white hue, but since the latter part of the 20th Century has been white.
