Mark Cosovich

Former pupils may be interested to know about the stunningly good restoration work that Mark Cosovich carries out on Mercedes cars at his Swansea business centre. He has recently published the first comprehensive English-language book on the legendary Mercedes-Benz W123 Series. It fulfils the demand for a detailed analysis of the model. Co-written by Mark, who is an acknowledged and respected W123 specialist, together with the UK’s leading classic car author, Martin Buckley, the book has a foreword by ex-F1 Champion Jody Scheckter.

You can read more about Mark in two press articles, here and here.
A video in which Mark talks about his work and which includes details of how to obtain the book can be found here.
Video only here.

Marks’ foundation in Metalwork and Engineering was all done at the Old Boys Grammar School Workshop, and he has given a credit to his teacher, Mr Ken Williams, and the school in his book. Mark would very much like to contact Ken but so far has failed to locate him. If anybody knows the whereabouts of Mr Williams, please let us know so that the two can meet up again - after 40 years.

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 (opens in new window). 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 then 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 are at the former Blaengwawr, Aberdare High and Aberdare Girls (Plasdraw) buildings. For further details of the reorganisation scheme published in 2011, click here.

Trecynon School Clock

clock tower

The asking price of ‘The Old Clock Tower’ is £275,000. 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. 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 current owner is Ray Radnedge of Radnedge Architectural Antiques in Llanelli. In the article he says 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.
