When I was walking around the castle, it felt extraordinary. The lake was a dark blue, and with just one small boat sitting across the water, it truly felt like a special place to visit.

An interesting event happened here: Lord Muskerry defended the castle against Oliver Cromwell, making it the last stronghold to resist him.

According to prophecy, General Ludlow sent a large boat onto the lake, which resulted in the defenders surrendering shortly after out of fear.

Architecture And Notable Features Of Ross Castle

The castle was built primarily for defence rather than aesthetic appeal.

The thick limestone walls provided strong protection against attackers.

An outer defensive wall surrounds the castle. Today, visitors can freely explore both the castle grounds and interior.

It features a classic tower house design, complete with a banqueting hall and minstrels’ gallery on the upper floor.

While four towers once overlooked the site, only two remain standing today.
