Mathias Spieler

Mathias Spihler (c. 1640 – February 1691) was a Swedish architect and master builder of German descent.

In the latter half of the 17th century, Marshal of the Realm of Sweden Johan Gabriel Stenbock (1640-1705) brought the Sjöö estate in the parish of Holm in Enköping.

Together with Mathias Spieler and architect Nicodemus Tessin the Elder (1615-1681), Stenbock built Sjöö Castle on his estate.

Sjöö Castle Palace with its park is considered one of the most beautiful in Sweden, with its perfect and harmonious proportions.

He is buried in Kungsholms kyrka (Ulrika Eleonora Church) which he built in 1672.
