The Pentland Skerries consist of four islands or skerries and three rocks (the smallest rock is 135 m2)[4]. The major islands include Muckle Skerry, Louther Skerry, Clettack Skerry and Little Skerry (Figure 2). The area, coastline and geo-location of the main islands in the Pentland Skerries are shown in Table 1.
The total area of the Pentland Skerries is 0.55 km2, the coastline of the Skerries is 7.78 km. The biggest island of the Pentland Skerries is the Muckle Skerry, with the area of 0.50 km2, the coastline of 5.03 km, and elevation of 0-20 m. The Pentland Skerries is uninhabited. The light towers (Figure 3), including the north high tower and the south low tower, were built on the Muckle Skerry in 1794[6].
