Also known as Melin Llynnon, Llynnon mill is the only working windmill on Anglesey. Next to the mill, you can visit a reconstruction of an Iron Age Settlement which would have stood here around 3 - 5,000 years ago.

When you finish learning about flour production and historic life on the island, you can stop for a delicious meringue and a cup of tea at the cafe.

Four Mile Bridge

Highlight • Bridge

The bridge itself takes the same name as the village it is situated in and is one of three bridges connecting Holy Island and Anglesey. The bridge is approximately four miles (6.5 km) from Holyhead via the old road route, giving it, and the village, its name. A bridge at this location was in existence by 1530, and was the only land route to Holyhead until the construction of the Stanley Embankment in 1823. It is 120 metres (390 ft) long and carries the B4545 road over the Cymyran strait.

I think the crossing over the water is about 5km
