Seafield Tower

To the south of Seafield Tower, which is a sixteenth century castle ruin built of local red sandstone, is a highly fossiliferous section of Carboniferous Limestone. The limestone is packed with beautifully preserved crinoids, bryozoans, corals, shells and, if you are lucky, sharks’ teeth. These are exposed on the foreshore platforms.
