The reopening of Carloway Broch is set to take longer than originally expected.
The visitor attraction was scheduled to reopen on 1 August.
However, an update given to Historic Environment Scotland on 25 June reveals there is now no structured time frame for the broch's reopening.
It is understood that public access is temporarily denied as work is carried out to loose masonry.
The broch visitor centre remains open for anyone wishing to explore the centre and look at the broch.
