Some doubts have recently been cast on just how much Irish influence there was at Dunadd, and the recent digs there have produced very little hard evidence of this. The archaeologists are now beginning to doubt the perceived wisdom that Dunadd was an Irish outpost - it may in fact have been 'locals' developing their own area. I have no doubt that there was a degree of traffic between the northern Irish and the Dalriatans, but there is more evidence being uncovered all the time that Dunadd was an important trading and manufacturing centre in its own right. One thing I remember reading was that moulds had been found which would have produced jewellery similar to the Hunterston broach found in Ayrshire.
The gate is aligned approximately ESE (around 120 degrees) towards the gap in the hills visible in the photograph.
