word usage - Is it correct to say "under the shelter of X, a Y was taking place?"

Is it correct to say the following?

All that could be heard was the wind blowing, and giant waves
crashing against the rocks in the beach. Under the shelter of
the inn, a barbecue was taking place.

Meaning that some people are having a barbecue right in front (or behind) of the inn. And this is partially protecting them from the wind.

Answer

"Under the shelter of [something]", is probably the more correct choice when the shelter is provided by something concrete, as in your question.

"Under shelter of" (without the 'the') is perhaps used with more abstract objects ("under shelter of the night", "under shelter of confidentiality").

Both seem to be widely used to mean "sheltered by".

"In the shelter of the inn" would, in my view, imply being inside the inn.
