Gimmersta herrgård, Manor estate in Katrineholm Municipality, Sweden.

Gimmersta herrgård is a classical-style manor house with four separate wings and balanced architecture in southern Sweden. The building features a wrought iron gate bearing the Bonde family coat of arms and is surrounded by agricultural outbuildings, large barns, and a yellow-plastered stable with a clock dating from 1674.

Gimmersta is first mentioned in 1262 as Gymbristada, owned by Filip Elofsson, a nephew of Birger Jarl. In 1462 the knight Magnus Gren gave it as a morning gift to his wife Gertrud Narvesdotter; through their daughter Philippa's marriage to Bengt Ryning it passed to the Ryning family, held until the mid-1600s. Marriage then brought it to the Ribbing family, and in 1805 David Gotthard Henrik Hildebrand bought it, incorporating it into the Ericsberg estate. Since 1828, when it was sold to Knut Filip Bonde, it has belonged to the Bonde family.

The name Gimmersta derives from the 1262 form Gymbristada. The estate's bell in the yellow-plastered stable clock tower bears the inscription of Leonardus Ribbing, Baron and Lord of Gimmerstad, dated 1674. The wrought-iron gate at the road entrance is decorated with the Bonde family coat of arms, marking nearly 200 years of Bonde ownership since 1828.

The buildings stand about 500 metres south of Julita church, reached along a 2,000-metre horse-chestnut avenue (länsväg 596) that runs straight through the estate; the Gimmersta bus stop is on this road. The main building and four wings enclose a gravelled forecourt, with the farm buildings across the avenue. The estate is private, so view the exterior from the road and avenue.

The surviving orangery is a single room with four large south-facing windows, built of brick and plastered inside and out, measuring 7.00 by 21.15 metres. It originally had four chimneys, suggesting heating by four tiled stoves. An 1805 description noted unusually large fig and mulberry trees in the garden.
