I have a tourism website that contains popular parks, museums, temples, historical places and so on. All of them have some opening and closing time.

Now each of my categories has a type in Schema.org except tombs, forts and world heritage sites (in shot historical places). So what I did is, wrote only "TouristAttraction" in the "@type" field.

Now the problem is Google’s SDTT is saying:

The property openingHours is not recognized by Google for an object of type TouristAttraction.

as a warning in that case only.

So what type should I define for historical places so that I can also write their opening and closing timings without getting any warning from the SDTT?
