As it stood in 1510
The shape it held in its prime.
A compact stone-and-brick fortress occupying a plateau roughly 125 × 80 metres and 3–4 metres high, its built area concentrated toward the northwestern quarter where house foundations cluster. A continuous curtain of masonry ran along the western slope, now visible as a string of fallen blocks. The summit held courtyards and ranges of stone-built domestic buildings; the hilltop commanded direct views over the Almarestäket strait and the approaches to Görväln.
Its story
The story of Almare-Stäkets borg.
Almarestäket's castle — also called Sankt Erik's castle, after Eric IX of Sweden — was once counted among Sweden's strongest and most famous castles. It commanded the choke point of Almarestäket, the strait at the inlet to Lake Mälaren, from a low plateau in what is now Upplands-Bro municipality in Stockholm County.
During the domestic political strife of the 1510s the castle was held by Bishop Gustav Trolle, whose main opponent, Sten Sture the Younger, besieged it in 1516–17. The castle was subsequently demolished, and the ruin is listed as an ancient monument by the Swedish National Heritage Board.
