Hallforest Castle is a keep, one of the oldest in Scotland, as it dates from the 14th century. The castle is believed to have been built by Robert the Bruce as a hunting lodge; he is said to have granted it to Robert II Keith, Marischal of Scotland, the predecessor of the Earls of Kintore. Mary, Queen of Scots visited Hallforrest in 1562.
The castle was frequently attacked during the 17th-century wars. It may have been abandoned shortly afterward, although it remains the property of the Earls of Kintore.
Hallforrest is a plain oblong tower 15 m long and 11 m wide. It once had a parapet, and probably a stone roof resting on an upper arch. It had two vaults, divided by entresol floors. It seems that the entrance led to the first entresol floor. There are small gun-loops to the basement, which may have had a cattle door.
Originally the castle had six floors. There are windows on the south. There is no evidence of masonry stairs; ladders and hatches must have been used. The interior is now ruinous.
To the north there are traces of what may have been an enclosing wall, and to the north west traces of a possible ditch or moat.
References:Stobi was an ancient town of Paeonia located near Gradsko. It is considered by many to be the most famous archaeological site in North Macedonia. Stobi was built where the Erigon (Crna River) joins the Axios (Vardar), making it strategically important as a center for both trade and warfare.
Stobi developed from a Paeonian settlement established in the Archaic period. It is believed that in 217 BCE, Philip V annexed Paionia during his campaign against the Dardani who had entered Bylazora, the largest Paeonian town.
The city was first mentioned in writing by the historian Livy, in connection with a victory of Philip V of Macedon over the Dardani in 197 BC. In 168 BC, the Romans defeated Perseus and Macedonia was divided into four nominally independent republics. In 148 BC, the four areas of Macedonia were brought together in a unified Roman province. In the reign of Augustus the city grew in size and population.
