🏛️ Attraction

Last updated: 23 May 2026

Overview

An Túr Faire, known as the Signal Tower, stands atop the highest point on Inisheer (Inis Oírr), the smallest of the Aran Islands. This stone structure offers one of the most commanding vantage points in the Atlantic, with views stretching across the ocean to the neighbouring islands of Inishmore and Inishmaan, and inland to the coast of County Galway. Today, the tower is a popular stop for walkers and photographers seeking dramatic scenery without an entry fee.

Inisheer is renowned for its rugged landscape, rich cultural heritage, and strong sense of community. The signal tower serves as both a historical landmark and a natural viewpoint, connecting visitors to the island’s strategic past and its breathtaking natural setting.

History

The tower is a remnant of Ireland’s Napoleonic coastal defence network. In the early 19th century, fear of a French invasion prompted the British administration to erect a chain of signal towers along the Irish coastline. An Túr Faire was built to relay warnings rapidly across the islands and to the mainland.

Constructed from locally quarried limestone, the two-storey tower originally featured a fireplace, a flag-staff socket, and a lantern base on the roof. A low surrounding wall once housed a guardhouse and storehouse for the watchmen. The watchmen would keep a constant lookout for sails, using flags and lanterns to transmit signals to adjacent towers. This system allowed for rapid communication of potential threats across vast distances.

The tower remained in active service until the early 1810s, when its signalling role was superseded by the island’s lighthouse. The structure has since been recognised as a national monument, preserving a tangible link to a tense period in Irish history.

Getting There

Ferry Access: Inisheer is accessible by regular ferry services from Doolin and Rossaveal on the mainland. The crossing from Doolin takes approximately 15 minutes, while the journey from Rossaveal is around 40 to 50 minutes. Ferries land at the sheltered pier in the main village. The ferry journey itself offers early glimpses of the island’s dramatic cliffs and the tower’s silhouette against the sky.

On-Island Transport: Inisheer is small enough to explore on foot, but bicycles and horse-drawn carriages are also available for hire in the village. The signal tower is located on a hill a short distance from the village centre. The route is well-trodden but involves a steep climb, so visitors should be prepared for a brisk walk.

What to See & Do

  • Panoramic Views: The open courtyard of the tower provides 360-degree views. On a clear day, you can see the full expanse of the Aran Islands, the Twelve Bens mountain range in Connemara, and the distant horizon of the Atlantic. The location is excellent for watching sunsets over the ocean.
  • Historic Features: Look for the original flag-staff socket and the remnants of the lantern base on the flat roof slab. The low wall surrounding the tower outlines the footprint of the former guardhouse where watchmen would have stood.
  • Walking Routes: The tower sits on a ridge that connects several key sites on the island. A popular loop walk links the tower with the island’s GAA pitch, the ruins of O’Brien’s Castle, and the Cnoc Raithní Bronze Age burial mound. This route offers a comprehensive overview of the island’s cultural and natural heritage.
  • Photography: The rugged limestone walls of the tower contrast sharply with the blue sea and green fields of the island. The structure is particularly striking when clouds gather over the Atlantic, creating dynamic lighting conditions. The surrounding landscape is a patchwork of dry-stone walls and grazing fields, typical of the Aran way of life.
