Ängsö Slott

Island Origins in Medieval Times

Ängsö Slott stands on an island in Lake Mälaren, first mentioned as Engsev in a 1167 letter from King Knut Eriksson, who inherited it from his father Erik Jedvardsson. By 1272, Riseberga Abbey traded the estate to Greger Birgersson, an illegitimate son of Birger Jarl. Archaeological evidence reveals human settlement here around 1,500 years ago, with three preserved grave fields containing 150 graves across what were once two larger islands surrounded by an archipelago.The island's core features about 60 small torp from the 1700s and 1800s, tied to the estate. These crofts, often just a hectare, housed families sustaining themselves on livestock like pigs, cows, sheep, hens, and horses, paying rent in labor, eggs, or grain. Four soldier's torp were added in the late 1600s; today, house foundations and clearance cairns evoke this bygone rural life.

Fortified Castle Construction

The current castle, a nearly cubic four-story building of stone and brick, originated around 1480 under riksråd Bengt Fadersson Sparre as a fortified stronghold. Its lower sections remain medieval. In the 1630s, Per Sparre expanded it, as depicted in Erik Dahlbergh's Suecia antiqua et hodierna. The 1740s saw Carl Fredric Piper add the top floor, mansard roof, and lanternin designed by Carl Hårleman, plus garden wings and a library focused on historical texts.Until 1691, Ängsö's lords held 'hals- och handrätt'—authority over life and death via a lagläsare and peasant jury, independent of any bishopric. Post-abolition, it fell under Västerås diocese. A church built circa 1340 anchors the island's center, intertwining with estate governance.

Sieges and Shifting Ownership

Bengt's son Knut Bengtsson, riksråd to King Kristian II, opposed Gustav Vasa. Shot in Västerås in 1521 defending the city, Knut saw Ängsö besieged and captured in 1522 by Vasa's forces, who partially destroyed it. Returned to Knut's daughter Hillevi Knutsdotter (married Arvid Trolle) in 1538, it passed through Trolle, Posse, and Sparre families until 1710.Christina Piper bought it amid her husband Carl Piper's Russian captivity. She established it as a Piper fideicommiss; uninhabited by her, it decayed before her son's restorations. Sparre held it from 1307-1710 across generations, shaping its turbulent noble legacy.

Ghostly Legends and Hauntings

Ängsö claims Sweden's most ghosts. Brita Bååt, infamous for driving two husbands to early deaths, haunts as a dragging female figure through the King's Room to the great ballroom at 8pm. On a Christmas Eve, rushing to church after dreaming of missed matins, she encountered skeletal figures—revenants of her spouses attacked with sword (now in church) and stone (bloodstone in churchyard wall), severing her veil; she died three days later.Puckery court jester Anders Luxemburg, last to see Karl XII alive, roams; his master's horse Brandklipparen died slamming into a stable wall in terror in 1740. Johan Sigismund Sparre received a golden chain from a shadowy dice partner, warned never to remove it lest the castle burn—it's displayed in the stairwell. Eva Sophia von Fersen's dog Cottilion's ghost appears, commemorated on its gravestone.

Modern Stewardship and Preservation

Piper owned it as fideicommiss until 1971, when Västerås city acquired it via Stiftelsen Westmannastiftelsen (2010-present). Uninhabited since 1959, it preserves rococo interiors. The estate reflects Västmanland's layered history—from Viking-era graves to Enlightenment expansions—inviting exploration of its atmospheric rooms and island landscapes.
