The majority of museums and tourist attractions are closed at the moment. The above linked articles show some virtual tours you can take until they reopen. Some are a little scary or creepy, but should be fun to see.
The above linked article tells about places that are offering virtual field trips. While you are working from home or quarantined, you can still see some of these places.
This is just a partial list. I heard that the Monterey Bay Aquarium is allowing people to watch the main tank while the aquarium is closed even before I saw this article. I am sure there are several others doing the same, that aren’t on the list.
Enjoy seeing the sites without even leaving home!
