Free walking tour Washington - Through the ancient history

The beautiful federal capital was founded in 1790, and it surprises everyone who comes to it for the first time, not only for its emblematic government buildings and architectural monuments of neoclassical style, as memorials in honor of the presidents, the Capitol or the White House, reminiscent of the grandeur of Greek temples, but for its parks, museums and other sites that you can see in 1, 2 or 3 days of travel that are usually dedicated to this city. First of all cultural background is needed to introduce the sights and the second I look at the group ages and finally, my high experience helps me to see what would be the best options to sell the tour.
