Miklós Ybl (Székesfehérvár, 6 April 1814 – Budapest, 22 January 1891) was one of the greatest Hungarian architects of the 19th century and a major figure in European revival architecture. His style was in essence Romantic, embracing the Romanesque and neo-Renaissance.
Ybl is notable as the designer of many apartment houses, palaces, country houses, public buildings and religious edifices. He was decorated with the Knight's Cross of the Order of Franz Joseph on 11 September 1865 and the Knight's Cross of the Order of Leopold in 1882, and was appointed a member of the House of Magnates by the king on 21 June 1885.
The Wenckheim Palace in Szabadkígyós was designed by Miklós Ybl in the neo-Renaissance and eclectic styles and built between 1875 and 1879. It was consecrated on 19 July 1882. The surrounding twenty-three hectare park has been a conservation area since 1954.
