Adelsnäs (formerly known as Näs) manor was named after Johan Adelswärd, who acquired the local copper mine in 1781. The present manor building was built Theodor Adelswärd in 1916-1920. English garden and parks around the Bysjön lake are popular when open to the public.

The unique detail is a “Sun Cannon”, which is installed in a red brick tower from 1853. It is a 6-pound cannon from the same period with an ignition system consisting of a magnifying glass mounted on a movable arm, adjustable to the sun’s different meridian latitudes. At exactly 1 pm, when the sun reaches its highest point at midday in summertime, the sun shines through this opening, hitting the magnifying glass focused on the priming compound at the back of the cannon.

Hi Rod, I think you could ask from Baroniet Adelswärd.

Can you please help me? I believe that my grandfather James Albert Page was the gardener on this estate from ~ 1911 to 1920. Can you direct me to where I can find out about this? In anticipation, many thanks.

Cháteau Comtal

The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.

The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.

The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
