The international conservation group Greenpeace accuses Spain of overdeveloping its Mediterranean coastline, which it says could cause irreversible damage.
Greenpeace says in a new report that Spanish developers plan to build more than 200,000 hotel rooms and hundreds of golf courses and marinas.
The group says Spanish police are currently investigating more than 100 cases of corruption that it says has led to illegal building along protected coastal areas.
Spanish officials have not yet responded to Greenpeace.
The European Parliament last week condemned Spain for what it called the disastrous effect development has had on the coastal environment.
