Harry Avery's Castle is situated half a mile south-west of Newtownstewart, Northern Ireland. It is a rare example of a stone castle built by a Gaelic Irish chief, although its origins and history are uncertain. It is associated with and named after Henry Aimhréidh O'Neill (died 1392), whose name was anglicised as Harry Avery.

The standing part of the castle comprises a two-storey rectangular construction fronted by massive D-shaped twin towers. Although having the appearance of a gatehouse, this structure was in fact a simple tower house with the D-towers added to the front. The tower comprised a vaulted basement entered from a large door between the D-towers. Above this was a hall on the first floor level, which was accessed from the courtyard. The southerly D-tower contained a spiral stair linking the two storeys, and both D-towers contained small rooms at first floor, with single windows in their round walls. Traces of a mural stair lead up from the first floor, and there is a latrine chute leading up, suggesting at least a parapet at the second floor. Examination of the structure suggests that it was built in a single phase, rather than being a modification of an older gatehouse.

The design of the castle has been compared to that of Elagh Castle, Inishowen, which also appears to have been a native-built castle featuring D-towers. The inspiration is thought have come from Norman castles such as Carrickfergus Castle and Castle Roche, both of which have true gatehouses flanked by D-towers. The overall design of Harry Avery's Castle is also similar to other Gaelic fortresses such as Seafin, County Down, which were later enclosed by a curtain wall with a tower house.

Harry Avery's castle is located high in the hills, less than a mile from Newtownstewart. There is no formal parking on the narrow road beside it, but you can park on the grass verge near the entrance gate. Access to the castle is a short distance across a farm field. There is a warning to be aware of cattle, but the field was empty when I was there. There's little left of the castle, but I spent a good 25 minutes wandering around it and admiring the panoramic 360 degree view. It would be possible to combine this with a visit to Baronscourt forest and estate.

Just a small piece of what used to be a castle. If you don’t mind walking/running your way through cows, it’s worth trying the little expedition! Just be careful if you drive there as there’s no place to park a car.

Monte d'Accoddi

Monte d"Accoddi is a Neolithic archaeological site in northern Sardinia, located in the territory of Sassari. The site consists of a massive raised stone platform thought to have been an altar. It was constructed by the Ozieri culture or earlier, with the oldest parts dated to around 4,000–3,650 BC.

The site was discovered in 1954 in a field owned by the Segni family. No chambers or entrances to the mound have been found, leading to the presumption it was an altar, a temple or a step pyramid. It may have also served an observational function, as its square plan is coordinated with the cardinal points of the compass.

The initial Ozieri structure was abandoned or destroyed around 3000 BC, with traces of fire found in the archeological evidence. Around 2800 BC the remains of the original structure were completely covered with a layered mixture of earth and stone, and large blocks of limestone were then applied to establish a second platform, truncated by a step pyramid (36 m × 29 m, about 10 m in height), accessible by means of a second ramp, 42 m long, built over the older one. This second temple resembles contemporary Mesopotamian ziggurats, and is attributed to the Abealzu-Filigosa culture.

Archeological excavations from the chalcolithic Abealzu-Filigosa layers indicate the Monte d"Accoddi was used for animal sacrifice, with the remains of sheep, cattle, and swine recovered in near equal proportions. It is among the earliest known sacrificial sites in Western Europe.

The site appears to have been abandoned again around 1800 BC, at the onset of the Nuragic age.

The monument was partially reconstructed during the 1980s. It is open to the public and accessible by the old route of SS131 highway, near the hamlet of Ottava. It is 14,9 km from Sassari and 45 km from Alghero. There is no public transportation to the site. The opening times vary throughout the year.
