A good parallel in English is actually “going to (or being at) school.” While you can say you’re at “the” school or “a school”, they mean different things than just being at school. Ditto for UK “to hospital.” (Cf. to university, to college, to city hall, in government)
Notably these are not the norm in English, but they do illustrate the pattern.
