A view of the meeting room at the current NATO headquarters in Brussels on November 13, 2013. NATO allies at the Washington Summit in 1999 decided to replace the existing headquarters and build new NATO headquarters directly across the street. NATO has been based in the same building since 1967 and since then the number of NATO members has nearly doubled from 15 to 28 countries. The new headquarters, currently under construction, are scheduled to open in the spring or early summer of 2016.
