The National Mall in Washington DC is about 45 minutes away. Here you will find most of the DC monuments and many large museums, as well as countless other things to do in the city. This is a great place to spend the day, though note there can be a lot of traffic if you are planning to go the day of the wedding so please give yourself at least and extra hour at least to get back :)
