#  Tours 

 



## Scheduling

For tours of the Glass Plate Collection, please contact [harvardplatestacks@cfa.harvard.edu](mailto:///harvardplatestacks@cfa.harvard.edu). Please give two or more weeks notice. Also because of Harvard rules, groups with those under 18, will require longer lead time.

## Accessibility 

We are committed to supporting all visitors to the Observatory. Unfortunately we are constrained by the 19th (and 20th) century buildings in which our collections are stored. For this reason, please specify if your tour will include wheelchair users. We can provide virtual tours of the Plate Stacks and Great Refractor, along with the oportunity to view archival objects and ask questions, without entering inaccessible spaces.
