Nicodemus Tessin was born in Nykœping in 1654. His father and namesake belonged to an old Pomeranian family, and had come to Sweden during the reign of Queen Christine. Nicodemus Tessin, Senior, was an able architect, who built the castle of Drottningholm for Queen-dowager Hedvig Eleonore, a moderately gifted but art-loving woman. The latter gathered around herself artists and architects at her castle of Drottningholm, in Lake Mælar, among whom were Ehrenstrahl, a famous artist of German birth, who founded the first school of Swedish painters. The younger Tessin belonged to this circle and was, in their respective times, in the favor of Charles XI. and Charles XII., acting as court architect to both. The work which won for him an immortal fame is the royal palace of Stockholm, an architectural creation worthy of the admiration of all Europe, and, in Sweden, standing unsurpassed to this day. It was planned and commenced by Tessin, but completed according to his plans a hundred years after his death. Charles XI. ordered a reconstruction of the old castle, which enterprise Tessin undertook. Shortly after the death of Charles XI., both the old and the reconstructed parts of the palace were burned, and the body of the king with difficulty saved from the conflagration. Charles XII. ordered Tessin to build an entirely new palace. The work was commenced in 1698, but was gradually abandoned during the war times, to cease shortly before the battle of Pultowa. Charles was highly interested in it and wrote from Turkey to Tessin about his views. Tessin intended to decorate the exterior according to the taste of his day, but Charles raised opposition, finding the severe beauty of the stern yet graceful outlines perfect in themselves. The work on the new palace was recommenced after the death of Charles XII. King Adolphus Frederic was the first who took up his residence within its walls. Tessin rose high on the social ladder. From Turkey, the king made him a count and chancellor of the University of Lund; after his return to Sweden he appointed him marshal-colonel. Tessin stood in strong opposition to Baron Gœrtz, and after the death of King Charles joined the leaders of the revolutionary nobles. He was of universal fame.
