The harbour at Rush, such as it is.
Just off the coast, is what I believe is Lambay Island, accessible by boat from Rush. In the 8th century, the island was the scene of one of the first Viking incursions. There are still some fortifications dating from 1550. Now a bird sanctuary, it can only be visited with permission from its owner, Lord Revelstoke. Click for a close up of the island.
Looking further north towards Skerries. On the very point of land there is a Martello Tower visible in close up. There are 74 Martello Towers erected around 1804 at vulnerable points along the coast. They are about 12m (40 ft) high, with 2.5m (8 feet) thick walls, and usually had 2 or 3 guns.
Looking across the bay at Skerries. Those clouds are beginning to look ominous, and indeed we were about to see the last of the sun for a few days. This and the next photo were taken from an area that originally was an island.
Looking back towards the "mainland". These buildings are on the filled in land which turned the island into a headland.
After Skerries we continued north, reaching the main road and Drogheda, where we decided to follow the local custom and consider this a long day's journey and stop for the night. One benefit of travelling in October is that (with one exception) we never had trouble finding a place to stay. And so it was with Drogheda.
