Which states should be home to the biggest new hotels?
The number of hotels on the National Register of Historic Places fell sharply over the past year to the lowest level since the first survey began in 1980.
The real estate market is expected to be buoyed by the launch of the $2.9 billion Marriott International hotel in the Florida Keys.
The hotel will include an indoor swimming pool and a spa.
The National Register’s last survey found that there were 1,945 hotels and inns in the country, down from 1,851 in 2010.
The number of national monuments increased by 20 percent over the previous year to 1,534.
The last survey also found that nearly all of the country’s natural areas, including the Great Lakes, had been declared national parks.
New Orleans, which was designated as a historic district in 1990, had the biggest increase in the number of historic sites, up by 17 percent.
New York City had the second-largest increase, by more than 10 percent.
Some of the largest increases in historic sites are in New Mexico, which had more than 100 new sites in the top 10, followed by Texas, which saw more than a dozen new sites.
One big reason for the jump in the rankings of national parks and historic sites was the launch in April of the National Historic Trails National Park System.
