The name of the school, "CWM Derwen Comprehensive" is shown (at around 27 mins) on the gate and can also be seen at 88:27 in the crest on Taliesin's school jumper (pullover sweater). From the Welsh language, "cwm" means "valley" in English and "derwen" means "oak tree". In the United Kingdom, a comprehensive school is a secondary school for children from the age of 11 to at least 16. CWM Derwen Comprehensive could then be translated as Oak Valley Secondary.
While Taliesin maintains (at around 64 mins) that pomegranates always have 611 seeds each, Jewish tradition teaches that the pomegranate is a symbol for righteousness because it is said to have 613 seeds which corresponds with the 613 mitzvot or commandments of the Torah. A web site (aquaphoenix.com) records that counting the seeds in 206 pomegranates from 6 countries resulted in a minimum of 165 seeds and a maximum of 1370 seeds, but achieves an average of 613.
