The ABGS Old Clock Tower House asking price has been reduced by a further £25,000 bringing it to £250,000 Freehold. WalesOnline has a report about the proposed sale dated October 8th.

Windows 10 Edge Browser
I have discovered that viewing the ABGS website with the ‘Edge’ Browser which is part of Windows 10 causes many of the webpages to behave erratically. For the time being visitors to the website who use Edge are asked to use instead Internet Explorer which is also part of Windows 10, or, any other browser such as Firefox. The pages that are affected are those that 'pop-up' individual photographs or pages of text such as those of The Aberdarian, the Certificate Ceremony Programmes and exam papers etc. Unfortunately there are hundreds of such pages, which have been added over the last 14 years, exhibiting this problem. You will often find the expected pop-up hiding behind the page you are viewing instead of in front of it! It will probably take some considerable time to re-code the problem areas.
I have also discovered that some Apple devices display the same type of pages unsatisfactorily. I have attempted to make this month’s 1914 edition of The Aberdarian display properly on all devices. Please let me know if you still have problems. (CR.)

Hand-held devices
Much of this website is devoted to displaying photographs or documents that require large displays for clarity view and of the typeface. The website was established back in 2001 when almost everybody used computers with reasonably large displays. Nowadays, many visitors visit the site using their smartphones and find that navigation using their touchscreens presents problems. Similarly reading documents on the small screens of smartphones is not straightforward. I am sorry that this happens, but I think that the use of a laptop, desktop or large screen tablet is probably the only realistic way of viewing most of the content presented here.

Cwmdare Rd School

Some Background Information about Aberdare County School
The school building was completed in July 1894 but, for reasons explained in the History section of this website, opened two years later on September 28th, 1896 as The Aberdare Technical and Intermediate Schools with Head Master W. Jenkyn Thomas and four assistant teachers: two men and two women. There were 141 pupils present by the end of the first term, 88 boys and 53 girls, taught in mixed classes for the majority of their subjects, although the building had separate entrances for boys and girls.

The school soon became known as The County School and remained so until the early sixties when the Grammar School name became more widely used. The pupils from the lower end of the Cynon Valley left in 1907 when Mountain Ash County School opened initially at Gwernifor, Miskin, moving to Dyffryn House much later in 1926. Then in 1913, the girls together with the women staff left for their own school in Plasdraw.

There was little significant change at the County School in terms of the nature of staffing and curriculum over the years until the Trecynon buildings were vacated in 1964 and the school relocated to the bottom of Cwmdare Hill.

In 1978 the Boys’ Grammar School closed and there was a fairly smooth transition to comprehensive status, when the Aberdare Boys Comprehensive School opened. Many of the existing staff were reappointed to the new school which was housed in the ex-grammar school buildings on Cwmdare Road, as the upper school. The buildings of Rhydywaun Secondary Modern School in Penywaun, which had also changed status, housed the lower school. The lower school at Rhydywaun was eventually brought to a new building at Cwmdare Road after two serious fires at Rhydywaun caused almost complete loss of its buildings.

From September 1st, 2009 Aberdare Boys Comprehensive School, was renamed Aberdare High School. The school adopted a new badge, which showed a similarity to the original grammar school design with ‘dragon and book’. The picture, above right, shows the school as it was in 1978, but additionally there was a large sports hall added to the site, behind the two-story block on the right. The new hall was both a school and a community facility.

In 2011, the decision was made by RTCBC to close the Boys’ High School, the Girls Comprehensive (at Plasdraw and The Gadlys) and Blaengwawr Comprehensive School. It was intended that the pupils of all three schools would be housed in the new school to be built at The Ynys, near the centre of Aberdare, and which was initially planned to open in September 2014. By September 2014 Aberdare had three secondary schools instead of the existing five. The new Aberdare Community School did open in September 2014, but only in name, and a move into the incomplete new school buildings was deferred until 2015. The temporary homes of the new school were at the former Blaengwawr, Aberdare High and Aberdare Girls (Plasdraw) buildings. Pupils started moving out of these old buildings and moving into the new building in the summer term of 2015, with examination candidates remaining in the Cwmdare Road building to take their examinations. The Girls’ School and its 3 acres of land in Plasdraw was sold at auction on July 13th 2015 for £415,000.

Trecynon School Clock

clock tower

The asking price of ‘The Old Clock Tower’ house was reduced to £250,000 in early October 2015. The tower and adjacent room have been converted into a new home that featured in both the South Wales Echo and the Cynon Valley Leader in July 2009, and again in October 2015. The Echo article was particularly impressive with a three-page spread, including a full-page photo of the building on the front page of the homeWALES supplement. The owner at the time of the Echo article was Ray Radnedge of Radnedge Architectural Antiques in Llanelli. In the article he said he initially purchased the clock only. But he then heard that the tower was to be demolished by the developer, so he bought that too. The inside pages show several views of both the exterior and of the internal fittings. Details of the property can be seen on the estate agent’s website by clicking here.

A gallery of photographs showing the reinstatement of the clock can be found in the School Building section of this website. The weather vane now completes the architectural fittings at the top of the dome, and the clock faces are now illuminated at night. The clock, which had been removed for restoration and repair, consists of a two-and-a-half tonne structure made of solid oak with cast iron facings, copper roof, and a 10 ft pendulum.
