Kronoberg Castle is a medieval ruin located on an island in lake Helgasjön. In 1444 Lars Mikaelson, the bishop of Växjö, built a stone building on the lakeshore. During the Dano-Swedish War of 1470-1471, Danish forces destroyed the house. It was reconstructed and fortified after peace was restored in 1472. During the Swedish Reformation the castle and its estate were confiscated by Gustav Vasa.
In 1542, during the Dacke War, Kronoberg was taken over by rebels led by Nils Dacke. The revolt was suppressed in 1543, and control reverted to the crown. Due to its strategic location near the border between Sweden and Denmark at the time, the castle was further fortified, and became a stronghold in this part of Småland. The king's son John III ordered additional improvements that never were carried out. The castle had great military significance during the Northern Seven Years War (1564-1570). In the winter of 1568, Eric XIV used Kronoborg as a support point while beating back a Danish attack from Skåne. In 1570 the castle was successfully besieged and burned by the Danes. Between 1576 and 1580 construction continued, after which the castle had at least 50 cannon. Duke Charles continued work on the fortifications, but in the end of January 1612 the castle was again taken and burned by Danish troops under Breide Rantzau. Reconstruction was not started until 1616.
As late as the reign of Charles XI Kronoberg castle was in good condition. However, after the Treaty of Roskilde was signed in 1658, the Swedish-Danish border was moved to Øresund, and Kronoberg castle lost its military significance. Neglected, the building began to decay and became a ruin.
The castle ruin is open to tourists in the summer months. It is located just short drive from Växjö, Sweden.References:
Pembroke Castle is a Norman castle, founded in 1093. It survived many changes of ownership and is now the largest privately owned castle in Wales. It was the birthplace of Henry Tudor (later Henry VII of England) in 1457.
Pembroke Castle stands on a site that has been occupied at least since the Roman period. Roger de Montgomerie, 1st Earl of Shrewsbury founded the first castle here in the 11th century. Although only made from earth and wood, Pembroke Castle resisted several Welsh attacks and sieges over the next 30 years. The castle was established at the heart of the Norman-controlled lands of southwest Wales.
When William Rufus died, Arnulf de Montgomery joined his elder brother, Robert of Bellême, in rebellion against Henry I, William's brother and successor as king; when the rebellion failed, he was forced to forfeit all his British lands and titles. Henry appointed his castellan, but when the chosen ally turned out to be incompetent, the King reappointed Gerald in 1102. By 1138 King Stephen had given Pembroke Castle to Gilbert de Clare who used it as an important base in the Norman invasion of Ireland.
In August 1189 Richard I arranged the marriage of Isabel, de Clare's granddaughter, to William Marshal who received both the castle and the title, Earl of Pembroke. He had the castle rebuilt in stone and established the great keep at the same time. Marshal was succeeded in turn by each of his five sons. His third son, Gilbert Marshal, was responsible for enlarging and further strengthening the castle between 1234 and 1241.
Later de Valence family held Pembroke for 70 years. During this time, the town was fortified with defensive walls, three main gates and a postern. Pembroke Castle became de Valence's military base for fighting the Welsh princes during the conquest of North Wales by Edward I between 1277 and 1295.
Pembroke Castle then reverted to the crown. In the 15th and 16th centuries, the castle was a place of peace until the outbreak of the English Civil War. Although most of South Wales sided with the King, Pembroke declared for Parliament. It was besieged by Royalist troops but was saved after Parliamentary reinforcements arrived by sea from nearby Milford Haven. Parliamentary forces then went on to capture the Royalist castles of Tenby, Haverfordwest and Carew.
In 1648, at the beginning of the Second Civil War, Pembroke's commander Colonel John Poyer led a Royalist uprising. Oliver Cromwell came to Pembroke on 24 May 1648 and took the castle after a seven-week siege. Its three leaders were found guilty of treason and Cromwell ordered the castle to be destroyed. Townspeople were even encouraged to disassemble the fortress and re-use its stone for their purposes.
The castle was then abandoned and allowed to decay. It remained in ruins until 1880, when a three-year restoration project was undertaken. Nothing further was done until 1928, when Major-General Sir Ivor Philipps acquired the castle and began an extensive restoration of the castle's walls, gatehouses, and towers. After his death, a trust was set up for the castle, jointly managed by the Philipps family and Pembroke town council.
The castle is sited on a strategic rocky promontory by the Milford Haven Waterway. The first fortification on the site was a Norman motte-and-bailey. It had earthen ramparts and a timber palisade.
In 1189, Pembroke Castle was acquired by William Marshal. He soon became Lord Marshal of England, and set about turning the earth and wood fort into an impressive Norman stone castle. The inner ward, which was constructed first, contains the huge round keep with its domed roof. Its original first-floor entrance was through an external stairwell. Inside, a spiral staircase connected its four stories. The keep's domed roof also has several putlog holes that supported a wooden fighting-platform. If the castle was attacked, the hoarding allowed defenders to go out beyond the keep's massive walls above the heads of the attackers.
The inner ward's curtain wall had a large horseshoe-shaped gateway. But only a thin wall was required along the promontory. This section of the wall has a small observation turret and a square stone platform. Domestic buildings including William Marshal's Great Hall and private apartments were within the inner ward. The 13th century keep is 23 metres tall with walls up to 6 metres thick at its base.
In the late 13th century, additional buildings were added to the inner ward, including a new Great Hall. A 55-step spiral staircase was also created that led down to a large limestone cave, known as Wogan Cavern, beneath the castle. The cave, which was created by natural water erosion, was fortified with a wall, a barred gateway and arrowslits. It may have served as a boathouse or a sallyport to the river where cargo or people could have been transferred.
The outer ward was defended by a large twin-towered gatehouse, a barbican and several round towers. The outer wall is 5 metres thick in places and constructed from Siltstone ashlar.
Although Pembroke Castle is a Norman-style enclosure castle with great keep, it can be more accurately described as a linear fortification because, like the later 13th-century castles at Caernarfon and Conwy, it was built on a rocky promontory surrounded by water. This meant that attacking forces could only assault on a narrow front. Architecturally, Pembroke's thickest walls and towers are all concentrated on its landward side facing the town, with Pembroke River providing a natural defense around the rest of its perimeter.
