Harvard University and
Visitas Registration Closed
Updated as of 10:07am
Harvard University will be closed Friday due to public safety concerns. Registration for Visitas is also closed until further notice. State officials have ordered residents to remain indoors and not to travel. Public transportation in Boston and Cambridge is currently closed. It is unclear when these restrictions will be lifted.
If you are planning to attend Visitas, but have not begun your travel to Cambridge, we ask that you do not begin your trip until after we have notified you that the campus is once again accessible. If you have begun your trip but have not yet arrived on campus, we note that it may be impossible to travel within the Boston/Cambridge areas and ask that you stay where you are for the time being. If you have arrived at Logan Airport, please do not attempt to travel to the campus until public safety authorities lift the travel ban and/or you hear from us.
We apologize for this inconvenience and share your disappointment that Visitas has been disrupted. But your safety and the safety of the public is of the utmost importance to us. We will be back in touch as soon as we have more information about when it is again appropriate to attempt to travel to Harvard
