June 13, 2025, The Bat Caves, Coed y Gopa

Site of Special Scientific Interest (SSSI): Coed y Gopa is designated as an SSSI due to its exceptional biological interest. Bats: It's particularly renowned for being home to the second largest lesser horseshoe bat hibernaculum in North East Wales. These bats utilize the numerous old mine workings (adits) and natural caves within the site for winter hibernation. Other bat species like Natterer's bat and Daubenton's bat are also found here. The wide rides and varied habitats within the wood provide excellent feeding areas for bats. Other Wildlife: Beyond bats, the woodland supports a rich array of wildlife, including various bird species like ospreys, goshawks, pied flycatchers, redstarts, and wood warblers.

August 5, 2024, Caer Seion Hillfort

In the second period a smaller and stronger fort was constructed at the west end of the hill. The older fort appears to have still been occupied but there was no access between the two. The smaller fort had somewhat wider walls and a strong gateway protected by bastions on either side and probably a ‘fighting tower’. Comparison with similar forts suggests that the wall would have been about 3 to 4m high with a walkway and breastwork wall on top. The defences were further reinforced by the addition of deep ditches at the east, north-east, west and south-west (E). The entrance was also protected by an ‘outwork’ – an outer wall that made rapid, approach to the entrance impossible and exposed any attackers to missiles from the defenders on the overlooking inner walls. The entrance through this outwork was later blocked. The excavations carried out in 1951 found a hearth inside one house in the small fort as well as spindle whorls (for spinning wool) and a quern (for grinding corn). In the large fort the house next to the entrance contained over 400 sling stones, so perhaps was a ‘guard chamber’. It may be that the small fort was built during the period between the first Roman attack on north Wales in 60AD and the final conquest in 78 AD. The absence of Roman period finds from the fort suggested that it was not occupied after the Roman conquest, and so it may have been destroyed and deserted. However, there is a tradition linking the fort with Maelgwn Gwynedd in the 6th century and it has been suggested that the small fort belongs to that period. Outside the fort are some remains of stone-walled roundhouses that may have been occupied at the same time as the fort or during the Roman period. One lies in a slight level hollow at the north side of the North Wales Path just east of the path up to the fort. It consists of one large roundhouse and probably several other smaller buildings. The other lies on a terrace on the slope below the south-east angle of the fort and consists of just a single large roundhouse.

August 5, 2024, Caer Seion Hillfort

Caer Seion is a large and strong hill fort. Excavations were carried out in 1951 but did not produce any dating evidence. However, it is believed to have been occupied during the Middle to Late Iron Age, about 300 BC to 1st century AD and it seemed likely that the fort was abandoned when the Romans conquered North Wales in 78 AD. The fort had a commanding position overlooking Conwy Bay and estuary and over the ancient trackway that followed the coastal ridge, continuing westwards towards Anglesey. The next nearest strong forts and possibly tribal centres are at Pen-y-dinas on the Great Orme, Pen-y-gaer above Llanbedrycennin and Braich y Dinas above Penmaenmawr. The fort had two periods of defence. In the first period a single stone wall of 3 to 4m width encircled the whole hill top apart from at the steep north side where no defence was needed. It had one entrance, at the south side, which would have had a timber gate. The greater width of the wall around the gate suggests it had a ‘fighting tower’ over it. Within the fort were over 50 timber round houses, many just behind the rampart at the south side (to shelter from the wind) and they are visible as circular platforms terraced into the hill slope. They varied in size from about 4m to 8m diameter and traces of walling survive at some of them. In one place there is a possible corn-drying kiln.

The Little Orme (Welsh: Rhiwledyn, also known as Trwyn y Fuwch, Trwyn y Gogarth and Y Gogarth Fach) is 141 metres (463 ft) in height, and is a HuMP (having a minimum Hundred Metre Prominence). It is one of two headlands situated at either end of Llandudno Bay, in Conwy County Borough, Wales. The other, larger, headland is the Great Orme. It has two summits, the higher with a trig point. The cliffs are a popular challenge for highly experienced rock climbers. The Coast Guard Rescue Unit use the Little Orme for training. Otherwise, it is a popular sightseeing location and walking/hiking site. The Little Orme was inhabited during the Mesolithic and Neolithic eras, notably the Pant y Wennol cave. A small hoard of Iron Age Celtic metalwork was found in a cave on the Little Orme. The medieval chapel of Blessed Mary of Penrhyn, abandoned in 1930 and now in ruins, is at the foot of the Little Orme in the grounds of Penrhyn Hall at Penrhyn Bay. On 14 April 1587, printing material for Catholic literature was found in a cave on the Little Orme, where it had been used by the recusant Robert Pugh (squire of Penrhyn Hall) and his Chaplain Father William Davies to print Y Drych Cristianogawl (The Christian Mirror), the first book to be printed in Wales. They had taken refuge there during the persecution of Catholics instigated by Queen Elizabeth I in May 1586. The Royal Artillery coastal gunnery school, 198 battery, was posted to Little Orme during the Second World War. Target practice was undertaken from the headland to anchored boats, and unspent ammunition and unexploded shells may still be encountered offshore. Gun emplacements and ancillary buildings were in situ until at least the early 1960s, but the site has since been 'landscaped'.
