Horse Guards has been around since the mid-1700s in #Westminster, and is the headquarters of the Household Cavalry, which escorts the Queen on ceremonial occasions. I knew none of this of course, but the building's beautiful architecture and the #London Eye peeking over the back caught my attention while I was wandering around the city. Definitely worth a stop. #visitlondon #visituk #uk #wanderlust #igers #igdaily #picoftheday #bestoftheday #instago #trip #vacation beautiful
