The castles around Sigtuna: Wenngarn, Steninge, Rosersberg, Skånelaholm and Skokloster

Wenngarn

Four kilometres north of town on the Garnsviken inlet. A 12th-century stone house became a Renaissance castle in the 1500s and a Baroque one in 1670 under Magnus Gabriel De la Gardie, with Jean de la Vallée as architect. In the 20th century it was a treatment home, then stood empty until restoration began in 2014. Today: hotel, restaurants, bakery, a three-hectare kitchen garden, the candle factory shop in the loft, adventure golf and a small new village of houses, Allébyn. The park is open. Cycle path from town in fifteen minutes.

Steninge Palace

On the shore of Lake Mälaren between Sigtuna and Märsta, designed by Nicodemus Tessin the Younger and built in the 1690s. The palace itself is closed to the public, but the park is open and the stone barn from 1873 is Steninge Slottsgalleria with shops, a garden centre, a café and the restaurant Steninge Bruk. The Christmas market in the stone barn runs from November to Christmas. Next to it, Steninge slottsby is growing, a new residential area. Six kilometres from Sigtuna, bus 575.

Rosersberg Palace

One of the royal palaces, south of Märsta. Built in the 1630s and remodelled for Charles XIII and Charles XIV John. The early 19th-century interiors are unusually untouched because the palace has not been lived in since 1860. The state rooms are open for guided tours from June to September. The palace hotel in the wings has a restaurant all year and a palace café in the state rooms in summer. The park sits right on the lake, with horses, sheep and goats, and from here the Ingegerd walking trail runs towards Sigtuna. Sixteen kilometres, its own commuter train station.

Skånelaholm

A pink 17th-century manor on Lake Fysingen, east of Märsta, owned by the Royal Academy of Letters. In normal years guided tours Wednesday to Sunday from May to September. In 2026 it is closed for roof and facade renovation. The park can be visited. Twenty kilometres.

Skokloster

Across Lake Mälaren, in Håbo municipality. Skokloster Castle is the largest private palace ever built in Sweden, constructed 1654 to 1676 for Carl Gustaf Wrangel and never finished, which is the point: one of the halls remains as the builders left it in the 1670s. A state museum with an armoury and a library. By car it is 40 minutes around the bay via Bålsta. In summer there is sometimes a boat from Sigtuna. Ask at the harbour.
