Machu Picchu is Peru’s top tourist attraction and one of the New Seven Wonders of the World. But protests over bus contracts left hundreds of visitors stranded last week, with trains and roads blocked by demonstrators. The unrest has reignited long-standing concerns about overcrowding, mismanagement, and access to the site. Now, the organization that gave Machu Picchu its Wonder title is warning that its status — and Peru’s global image — could be at risk. The World’s Tibisay Zea reports.

Note: An earlier version of this story incorrectly stated that Moises Bendezú Sandoval led the campaign that helped Machu Picchu gain its status as a New Seven Wonder. The overall vote campaign was organized by the New7Wonders Foundation, which in 2007 recognized Bendezú Sandoval for his local grassroots efforts. New7Wonders has since stated that it is pursuing legal action against him for alleged fraud, misrepresentation and online false impersonation issues.
