NK 1104 3826 Four trenches and three test pits were excavated, 24-26 January 2019, in the banks and interior of Blockie Head promontory fort (NK13NW 6), which cuts off the Blockie Head promontory, south of Peterhead. This is part of a larger work looking at Scotland’s promontory forts to add to the body of knowledge regarding this enigmatic monument type. The monument consists of at least three ditches cutting of the promontory enclosing an area of around 0.08ha. Excavations were targeted at the outer defensive works and on the interior.

Trench 1 targeted the innermost ditch which proved to be at least 2m deep indicating that the internal bank was at least 4m above the base of the ditch, not accounting for erosion or possible palisades or fences on top of the bank.

Trench 2 was placed over the southern portion of the second ditch. Various clay fills were identified in the ditch along with charcoal from the lower fills which was sampled for dating.

Trench 3 was placed over the entrance area to test for archaeological deposits. This revealed two large postholes, one of which was half sectioned. One posthole was positioned at the NE edge of the trench, with its northern half extending beyond the limits of the excavated area. The excavated posthole measured approximately 0.75m N-S by 0.81m E-W (though the full extent of the feature was not revealed) and was 0.63m deep. Considering their positioning, these posts may represent another defensive element such as a palisade.

Trench 4 was located within the interior around 7m from the entrance. Up to nine postholes were identified in the trench along with a floor layer. Charred roundwood and charcoal found in a 0.3m slot dug on the west side appeared to consist of a burnt wattle layer that had been destroyed by a fire. This layer extended beyond the trench and the full extent was not recorded. Two southern postholes showed scorching and redness on the natural surface indicating in-situ burning. Samples from postholes and the floor layer were retrieved for dating. Four test pits were opened on the eastern side of the fort interior. None produced any archaeological features, but one trench located on the edge of the stack had 19th-century pottery which indicated this, a low bank around the edge of the interior, may be a later feature.
