Closing a rural school and sending pupils to a new one a few miles away could threaten the future of an entire village, the High Court has heard.
Campaigners have lobbied for two years against closure plans
Children in Hermon, Pembrokeshire, could lose their identity if they had to travel to nearby Crymych, which has a different "atmosphere", the Cardiff hearing was told.
The court heard that parents feared that closing it could make their children more likely to leave the area for good eventually.
In April, parents of the 53 pupils were given permission to challenge Pembrokeshire Council's closure decision.
Nicholas Bowen, representing the parents, told Mr Justice Jack:
"Parents fear that if they lose the school then the future of this village is
Hermon has a population of 300 and has a pub, hairdresser, two chapels, a
garage, florist and ironmonger, he said.
The council's decision would see pupils of Hermon school and another in
nearby Blaenffos transferred to a new £1.5m area school in Crymych, which has about 600 inhabitants.

Building work is due to be carried out in the coming academic year, with
pupils of the new school being taught at three sites until it is complete.
But Mr Bowen said: "Parents may not wish their children to travel for fear

"The thrust of the parents' case is that there is something very special in
Welsh terms about this type of village. Hermon is a village where the language
of the playground is automatically Welsh."
Crymych, however, has a different "atmosphere", he told the court.
He added: "Here, a significant number of families are Welsh language speakers as a
second language, not as the first language," he said.
"The bulk of parents at
Hermon are dedicated Welsh-speakers. It is the language of home, rather than an
alternative language to English."
Mr Bowen told the court on Monday that Hermon school, which opened in 1875, had a
"unique, nurturing atmosphere" where the parents were close and cohesive.
Admitting it was a "very contentious" point, the barrister claimed: "It is
a marked feature of this case that Pembrokeshire (council) have really sought to
eradicate small village schools from the county and have been largely
The council has argued that the £1.5m new school will have better facilities for all children.
The hearing is due to last for three days.
