chairman of the governors, in 1955 bequeathed to the school a small plot of land. Known as "Dr. Archer's plot", this was to be planted with flowers and kept for ever green. In 1957, several events commemorated the fourth centenary of the school. A new stained glass window was installed in the building to mark the event. 1971 Reorganisation Up to 1971, Friars had been a grammar school for boys. As a grammar school, education was selective, boys having to pass the eleven plus exam to gain admission. A significant reorganisation in 1971 combined three schools – Friars School, the Bangor County School for Girls (also a grammar school), and Deiniol School, a co-educational Secondary modern school. The three schools brought together formed a new comprehensive school, under the Friars name, but on three sites. The former girls' school became the Tryfan site, a Welsh language medium for the lower years, while the Ffriddoedd building was the location of the English language medium lower years. The senior years came together at a new building, built for £300,000 on a new site at Eithinog. A further reorganisation in 1978 split the school in two: Ysgol Tryfan was formed as an 11–18 Welsh medium school on the Tryfan site. Friars School became a mainly English-medium school on Ffriddoedd and Eithinog sites. Shoddy building practices of the 1960s meant that the Eithinog building had to be almost completely rebuilt over the following few decades. These were gradually replaced and expanded, until the whole school was able to relocate to Eithinog in 1999. The final contract for completing the school was valued at £5.4 million. In that year, the former Friars building at Ffriddoedd was sold to further education college Coleg Menai and continues in educational use. Celebrating 450 years A service of commemoration and thanksgiving was held in Bangor Cathedral in April 2007 to mark 450 years of Friars School. The modern school Since 1999, the present school has been united on the Eithinog site. It is a comprehensive school for the 11–18 age group, and draws pupils from a wide area around Bangor. The school's current student body totals 1346, with many pupils travelling from Anglesey, North Arfon, the Llŷn peninsula and further afield. Ysgol Friars is the largest secondary school in Gwynedd and one of the largest in North Wales. The current headteacher is Neil Foden. The school is also a
