And after he had finished studying Sparwenfeld went to search for old Swedish manuscripts in The Netherlands, France and Italy.

In 1674, he was brought by his uncle, amiral Claes Uggla, on a voyage to the Duchy of Holstein.

And during the Scanian War (1675–1679) he was captured and brought to England when a Danish corsair caused the ship to sink.

During his visit to Russia, Sparwenfeld became interested in Slavic languages, he began to learn Russian and did so really well.

In September 2020 Sparwenfeld and his estate Åbylund in the parish of Romfartuna in Sweden were depicted in the SVT-series Det sitter I väggarna.
