Drumbo Round Tower lies within the grounds of the local Presbyterian church. Historically the tower was attached to a medieval parish church and monastery, the foundations of which can be seen in the modern day graveyard on the site.
The tower dates from around the early medieval period and is a scheduled historic monument. The original structure was severely damaged when the site was plundered by Connor, son of Artgal McLochlin in 1130.
The site of the Drumbo round tower and medieval monastery is one of the oldest religious foundations in Ireland. In the life of Saint Patrick, which is contained in the Book of Armagh, the name Drumbo signifies 'the long hill of the cow,' which was translated into Collum Bovis, a name by which the ancient church was known. The round tower was originally built here to take advantage of the panoramic views over the Lagan Valley. At the time of the tower's construction, these views would have been useful in spotting incoming Viking raids.
The tower survives to a height of 10.7 metres. It is 5 metres in diameter, with an internal diameter of 2.75 metres. The wall is about 1.2 metres thick. The entrance in the east is 1.5 metres above ground level and is 1.68 metres high and about 0.56 metres wide. Inside there are beam holes indicating that the internal floors were of timber and there are six surviving levels including the basement.
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.
