Mathias Spieler

Mathias Spihler (c. 1640 – February 1691) was a Swedish architect and master builder of German descent from Södermalm, . In 1670-1 he aided Jean de la Vallée in the construction of Katarina Kyrka (Catherine's Church) and him as technical superintendent at the church in 1671. Spihler also built the Van der Nootska Palace between 1671 and 1672.

In the latter half of the 17th century, together with the Swedish architects Nicodemus Tessin the Elder (1615-1681) and Mathias Spieler, the Marshal of the Realm of Sweden Johan Gabriel Stenbock (1640-1705) brought Sjöö Castle in the tiny Parish of Holm, Enköping, Sweden, to the shape and form in which it is today. The Sjöö Castle Palace with its park is considered one of the most beautiful in Sweden, with its perfect and harmonious proportions.

Spieler was married to Margaret de la Vallée, daughter of Jean de la Vallée. Spieler died in Stockholm. He is buried in Kungsholms kyrka (Ulrika Eleonora Church) which he built in 1672.
