There were 50 signal towers during the Napoleonic because these particular towers were erected as a type of coastal defence that would alert the rest of the country of French invasion.

​

All towers are places strategically so that each tower will give off signal in sequence until all the coast is lit up!

​

There are 12 towers built in North Dublin. the First being at Red Rock Sutton Creek.

​

The only Tower available for viewing is Martello Tower because it was turned to a vintage  radio museum.

​

Its a popular tourist spot especially during the summer because it beautiful panoramic views of Howth Harbour all the way to Portmarnock!

​

The Martello tower is the largest tower in all of Dublin. This because it can heavy calibre artillery weapons on its roof!

​

This ancient and weathered Martello tower is one of 2 buildings that were built on Howth and its companion the ancient ruin of St. Nessan's Church.
