The Mormon Temple is a huge and well-known landmark in the DMV. It's not been open to the public for the last 45 years, but all that is changing this week.
As of yesterday the temple has opened its doors to private tours and later this month the doors will officially open to the public. You may reserve shuttle and tickets to see the temple and its grounds starting April 28th and continuing for several months. If you would like to reserve your spot to see this DMV landmark you can find the calendar to reserve an available date and all necessary information here.
