Tynnelsö Castle, Medieval castle on Tynnelsö island, Lake Mälaren, Sweden
The stone fortress features a square layout with multiple floors, standing on an island northeast of Strängnäs Municipality.
Bishop Kort Rogge constructed the first stone castle in the 1490s, with the original first floor structure remaining intact to this day.
The castle served as a strategic military fortification in 1443, housing 24 firearms, multiple cannons, and an arsenal of crossbows.
The National Property Board of Sweden currently manages the castle, which remains closed while undergoing extensive restoration work.
During Bishop Sigge's leadership from 1449 to 1463, the castle maintained a garrison of 100 men, making it one of Sweden's strongest fortifications.
