The IWM is an amazing place to go. I cant imagine trying to build something like it today and what it would take
It has the capitol police securing it, but you are not prohibited from carrying concealed.
The museum in the basement portion is one of a kind and very well done. Make sure you go to the sanctuary/ reflection room in the top floor. It is breath taking and an area to reflect/pray/meditate….worth your time
The monument circle is also part of the IWM campus and has a civil war museum portion in it also if it is open, i know the monument was getting some work done.
Go! It is a state and national treasure
