- The Gateway
The Gateway is one of the most important monuments and also now one of the most unique in Glendalough, Ireland. It was originally two stories with protecting walls at each end, or antae. There is a stone that has a cross inscribed in it in the gateway. This tower is 30 meters high and 3.5 meters in the base.
- St Kevin's Cross
One of Ireland’s most unusual and largest high crosses can be seen at Glendalough. The huge cross is carved from one single piece of granite. The cross is unusual in that it is not pierced through the ring like most Irish High Crosses. (In other words there is no opening through the ring of stone intersecting the haft and arms of the cross. This is certainly the only high cross I have seen in Ireland that is unpierced like this. The arms of the cross are over a metre in length.A local legend surrounding the St. Kevin’s Cross at Glendalough says that anyone who can wrap their arms around the entire width of the cross body will have their wishes granted.
- The Round Tower
The most visible monument at Glendalough is the fine round tower. The famous Round Tower is about 34 metres high and is 16 metres in circumference at the base. It is still in near perfect condition even though it is almost 1,000 years old! The tower originally had six wooden floors and was connected by ladders. The four stories above the entrance are beautifully lit by a tiny window, while the top story has four windows. The tapering roof was redone in 1876 using the stones that were originally used.
- St. Kevin's Bed
Just to the west of the church is a small raised platform with a stone walled enclosure. This enclosure held a small enclave of monastic stone huts. Close to this is St. Kevin’s Bed. This cave set in the rock face about 8 metres above the lake is said to have been a place of solitude and prayer for St. Kevin and later St. Laurence O’Toole who used the cave a as a retreat. The cave is partly natural and partly man made and runs 2 metres back into the rock.
- The Cathedral
The largest building at Glendalough is the cathedral, which took many differnt phases from the 10th through the early 13th century. In the late 12th and early 13th centuries the chancel, sacristy, and north door were built and added on to this.
-The Priest's House
Nearby is the Priests’ House, which has been almost completely rebuilt from the stones that were used first based on a 1779 drawing of the original. At each end of this tiny building there is an arch. This cathedral may have housed relics of St. Kevins, but the original use is not known. Priests were buried here and that is where this building gets its name form.
- St. Saviour's Church
This is the most recently built church. This church was built around the same time as St. Laurence O'Toole during the 12th century. Inside the church is decorated with a lion, a serpant and two birds. The birds are holding a head inbewtween their beaks. There is also a staircase that leads from one room to the building connected to the church.
