Milking shed
A milking shed was an outbuilding where cows were milked.

In 2376, The Doctor, while in the guise of "Father Mulligan", asked Seamus, who had entered the Fair Haven church with a cow, if he'd taken a wrong turn on his way to the milking shed. Seamus then explained that spirit folk had turned Maggie O'Halloran into a cow. ()
