Mathias Spieler
Swedish architect (1640–1691)

Mathias Spihler (c. 1640 – February 1691) was a Swedish architect and master builder of German descent.
Biography
Spihler was born at Södermalm in Stockholm, Sweden.
He aided Jean de la Vallée in the design and construction of Katarina Kyrka (Catherine Church) as technical superintendent at the church in 1671. Spieler also built the Van der Nootska Palace between 1671 and 1672.
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. The construction work lasted from 1669 until 1679 resulting in the shape and form in which it is today. 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.

Why this record matters
The phrase “swedish architect (1640–1691)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Mar 31, 2026. The linked authority identifier is Q6185642. VIAF identifies the subject as 138613319. The Library of Congress control number is n2010044636. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1640, 1691, 1671 and 1672.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
