On 09/11/2001 there were three attacks made on America, including the Pentagon, where we lost a family member. The memorial at the Pentagon was dedicated on 09/11/2008. As of this date, no memorial in Pennsylvania or New York City has been built.
The United States government did not pay for the building of the Pentagon Memorial. The Pentagon Memorial Fund was founded by family members of the 184 men, women and children lost at the Pentagon on 9/11. It is a non-profit, tax-deductible organization. The Fund was created to raise the private funds necessary to design, build and maintain the Pentagon Memorial.
