Konstantīns Pēkšēns (March 8, 1859, Mazsalaca parish - June 23, 1928, Badkissingen, Germany; buried in Riga, Meža cemetery) is one of the most prolific Latvian architects, a notable author or co-author of works of the stylistic orientation of national romanticism. According to his projects, multi-story brick houses, wooden buildings, churches, a series of parish halls and other public buildings were built in Latvian cities and villages, and in Riga - more than 250 buildings, including the house on Alberta Street 12, which houses the museum "Riga Art Nouveau Center". The buildings designed by the architect are characterized by solid restraint and the logic of architectural forms, the use of natural building materials, elegant decorations of ethnographic and Latvian natural motifs. K. Pēkšēns was the first Riga architect who started accentuating the corners of blocks with towers or other similar structures.
