Tirefour Castle

Tirefour Castle, (or Tirefour Broch, also spelled Tirfuir and Tirrefour) is an Iron Age broch located 4 kilometres north of Achnacroish on the island of Lismore, Scotland [1]. Tirefour Castle is situated on a rocky height on the east coast of the island of Lismore [1]. The broch was probably built in the late Iron Age [1]. It was inhabited during the Roman era as shown by the discovery of an enamel brooch in the foundation layer [1]. Among the finds in the broch was a decorative pin from the 8th century and a Norse pin and rivets, dating from the 11th or 12th century [1]. Tirefour Castle has an almost circular floor plan [1]. The lower floor has a solid, dry stone wall [1]. The wall is on average 3 metres high and survives to a maximum height of 4.9 metres in the southeast corner [1].
