Being a natural defensive location at a key position on the River Clyde this rock has been defended and of strategic importance since the iron age.

These photos were updated in early May, 2024.

Its well-guarded entrance under the wall and up a narrow stairway makes it an ideal place to defend with just a few men.

The scaffolding to the right of the main entrance seem to be a permanent feature.

Moving the camera round to the left to give a side-on view of the entrance.

In front of the castle, by the River Clyde, is a small but popular park with excellent views across the river as well as east towards Erskine and west over to Port Glasgow, Greenock and Gourock.

From the north side, looking across the river.

Those rocks on the right that have fallen off the cliff face are pretty impressive.

In the bottom left is Dumbarton Football Stadium which can be seen if you clicktap this line.
