Abandoned Crofter's House, Isle of Harris, Scotland
This decaying old cottage is now used as a shelter for sheep. But as I ventured inside, treading carefully through the thick carpet of straw and compacted droppings, I found this poignant reminder of the life of the last inhabitants - a vase still placed on the mantlepiece; the drying rail above the gas stove; and the wooden chair in the corner, facing into the bare room.

Calanais Stones, Isle of Lewis, Scotland
A storm approaches the 'Stonehenge of the North.' At the time they were made from the local Lewisian gneiss, sometime around 2000 BC in the Bronze Age, the climate was warmer and drier than it is today, and boggy peat has long since replaced the greener landscape of the past ages.

Traigh Mheilein, North Harris, Scotland
This rusty buoy lies half buried in the sands of this remote beach. It may look a pleasant enough day - but in typical Hebridean fashion, we suffered several hailstorms blown by gale force winds during our half hour return along the steep rocky coast back to Huisinis!

Standing Stones of Stenness, Mainland Orkney, Scotland
I always try to capture the image I want in-camera; normally I would use a graduated neutral density filter on the camera to balance the intensity of light from the sky with the land, so that the exposure records detail in both halves of the frame. But here that would have the effect of making the bottom half of the central stone lighter than the top half, with an artificial line running across the middle. So instead here is a rare occasion that I've blended two exposures together - a technique known as HDR ('high dynamic range'). I shot two images - one exposed for the grass and stone, and one exposed for the sky; and then manually blended these together in Photoshop. It's the equivalent of using a GND filter in the shape of the standing stones of Stenness... but who has one of those?

Bayham Abbey, East Sussex, England
Founded in 1207 this Premonstratensian ruined abbey's remaining elaborately carved sandstone walls are incredibly well preserved.

Skara Brae, Orkney, Scotland
The 5000-year old Neolithic settlement of Skara Brae lies half buried in grass and sand on the edge of an encroaching beach.

Standing Stones of Stenness, Mainland Orkney, Scotland
Orkney has some of the most impressive neolithic archeological sites in the world, such as the famous 5000-year old village of Skara Brae and the impressive burial chamber of Maeshowe. Of the two biggest stone circles in the area, the Ring of Brodgar may have more stones and is bigger in scope, but the few remaining Stones o' Stenness have the tallest stones in Orkney - nearly 6 metres (19 feet) high. Radio-carbon dating shows that the site dates from at least 3100BC.

12-Sided Incan Stone, Cusco, Peru
An exceptional example of the just extraordinary skills of the Incas in building using giant carved blocks of stone which fit together without gaps inbetween (and no mortar!). The twelve-sided Hatunrumiyoc stone is part of an Incan palace in Cusco.

Wreck of the Helvetia, Gower Peninsula, Wales
One large timber and a few small studs mark out a rough shape of what was once the Helvetia. Most photographs show the whole wreck and its position on the beach, usually at sunset or sunrise, but I was drawn to texture and palette of the wood grain and mosses, and to the bent rusting nails protruding from the rot which once held these planks together. There's something creepy about this image; it has the appearence of a crocodile's mouth, or the legs of a spider, about to emerge from within...

Bodiam Castle, East Sussex, England
Soon after a crisp still winter sunrise, with the last wisps of mist rising from the moat.

Nabataean House, Petra, Jordan
A weathered facade and doorway, thousands of years old, hints at what was once surely an astounding, ornate and elaborately carved entrance.
