Hook Head Lighthouse, co. Wexford

A brilliant lighthouses and one of the oldest in Europe. You can have a guided tour and can go up to all the various levels almost to the top, from where the sea crashing against the rocks below is quite spectacular. Visitors shop, cafe, etc etc

Loop Head, co. Clare

Like most of our lighthouses, only reached by a long drive down a very narrow and precipitous track. The lighthouse itself is enclosed by a whitewashed wall which prevents you getting anywhere near it.

Tarbert Lighthouse, co. Kerry

This was taken on the ferry crossing from Tarbert to Killimer.

Mizen Head Lighthouse, co. Cork

Another brilliant lighthouse, reached by a long, narrow drive across spectacular scenery and then a bit of a walk around a headland over a narrow bridge to get here. Not a tower lighthouse, as the building is already at a height above sea-level. There is a bit of a tour around it and a shop too.

Greenore Lighthouse, co. Louth

Actually inside the dock area and so only viewed over a whitewashed wall

Drogheda North Lighthouse, co. Meath

On a track near the mouth of the Boyne estuary (south side) Light surrounded by wall within a private dwelling. This photo taken from the car as a large Alsatian prevented closer inspection!

Drogheda West Lighthouse, co. Meath

Along a track leading to the beach at Mornigton at the mouth of the Boyne estuary. Graffiti strewn. Within the grounds of a private house but good views from nearby.

Drogheda East Lighthouse, co. Meath

Along a track leading to Mornington beach on the south side of the Boyne estuary. Surrounded by a brick wall, the whole thing rather resembles an electricity power station. Views either over the wall or through the barred gate. Note Drogheda West Lighthouse in the background

Balbriggan Lighthouse, co. Dublin

Located at the end of the harbour wall in Balbriggan - Lighthouse could probably do with a bit of a clean up!

Killyleagh Lighthouse, co. Down

Is this a lighthouse? My Ireland road atlas says it is, but I can find no reference elsewhere to this light in Strangford Lough. This view from the harbour area of Killyleagh.
This is apparently Town Rock. A sector light was installed on top of the tower in 2011 as a means to augment the poor navigation aids in the Lough.
" Built sometime in the 19th Century to help guide vessels into Killyleagh, it would originally have had an open fire burning atop at night or in bad weather rather than a light."

Swan Island, Strangford

This is situated smack bang in the middle of the entrance to Strangford Lough. I didn't take the ferry, so this is taken from Strangford.

St. John's Point, co. Down

On a wild headland. The road goes all the way up there but there is a sign at a gate about 200 yards away saying "No Visitors Allowed" from where this photo was taken.
First established in 1844, the tower has been painted white, white with black bands (1902 - 1954) and the above colour scheme since 1954.

Rathlin Island Rue Point Lighthouse

I like lighthouses you can touch. This is on the south point of the island reached by a 90 minute walk down a track, then across a field (full of sheep droppings), past numerous seals basking and finally a little paved track leading over the rocks. Great views of the Northern Island and Scottish coastlines.
Built in 1915, destroyed by a storm in 1917, temporary light erected before this beauty was born in 1921.

Rathlin East Lighthouse (2)

Reached by a 20 minute walk from the village. (Keep going up the hill away from the harbour, heading north) A bit disappointed that a stone wall prevents you getting closer. Robert the Bruce allegedly had his spider encounter in a cave nearby. Built 1856. Also known as Altacarry Head, there is a low light here also, the white domed structure that can be seen between the light and the keeper's cottage in the top picture.

Rathlin West Lighthouse

Built in 1917, a spectacular setting at the far western edge of Rathlin.

The famous Upside Down Lighthouse in that the light is located at the foot of the building. This pic taken from the wall above at the end of a steep path down to the puffin-viewing platform. (The puffins incidentally are gone by mid-August, when I went) Reached either by a long walk or by a trip on the Puffin Bus which meets the ferry and brings people there and back for £5 per head.
