P is for Portmeirion

Portmeirion was designed and built by the architect Clough Williams-Ellis from 1925 to 1976, in the style of a Mediterranean village. He wanted to show how a naturally beautiful site could be developed without spoiling it. The results are truly spectacular.

The site has served as the location for numerous films and television shows (including Doctor Who), but is probably best known for being "The Village" in the 1960s classic television show The Prisoner.

The whole site is now a tourist attraction and is now owned by a charitable trust. It's located near to Porthmadog, in Gwynedd, North Wales.

M is for the Millennium Centre, Cardiff

The Welsh Millennium Centre is an arts centre in Cardiff. The 7.5 acre site contains a 1,900 seat lyric theatre, designed for opera, large scale musicals, ballet and contemporary dance – as well as a studio theatre, a dance house and orchestral hall.

The Centre has made numerous appearances in film and television including Doctor Who, as the latest series is produced locally by BBC Wales. The spin-off series Torchwood also features the Centre - in seasons 1 and 2 of the series, the team had their headquarters underneath the Water Tower in Roald Dahl Plass.

L is for Llanberis

Llanberis is somewhere we only discovered last year. The village is right at the foot of Snowdon, the highest mountain in Wales. It's the home of the Snowdon Mountain Railway, a narrow gauge rack and pinion mountain railway that takes you right to the summit. It's a popular centre for walking, climbing, mountain biking and pony trekking as well as water sports.

However, my breath was taken away by the magnificent Llanberis Pass, a unique glaciated valley and world class climbing spot. The valley is narrow, straight and steep-sided, with rocky crags and boulders on either side of the road.

B is for the Brecon Beacons

The Brecon Beacons is a beautiful and rugged area of  South Wales. It's a tremendous place for walking, with some spectacular views across the countryside.  The highest peaks in the area include Fan Brycheiniog to the west and Pen y Fan in the centre. The whole area is steeped in folklore - the Lady of the Lake legend from the story of King Arthur is said to come from Llyn-y-Fan Fach, the lake below the peak of Black Mountain, to the west of the Brecon Beacons National Park. One the biggest draws is due to the fact that the whole area has been granted Dark Sky Preserve status. 

Due to the relative remoteness and harsh weather of some of its uplands, the National Park is also used for military training. UK Special Forces, including the SAS and SBS, hold demanding selection training exercises here.
