The Mamaia resort in Constanța is experiencing significant environmental and structural transformations. In September 2026, the area focused on expansion through motorsport events, such as the Seaside Speed Race and Mamaia Rally Show, alongside urban redevelopment projects aimed at replacing existing structures with high-rise hotels and apartments.

By October 2026, reports indicated that the resort’s beaches had narrowed by approximately 40 meters over a six-year period. This reduction follows a multi-million euro sand nourishment project intended to expand the coastline. Technical officials from the Dobrogea-Litoral Water Basin Administration (ABADL) stated that the narrowing is not a technical failure, but rather a “calculated part of the coastal engineering project” designed to accommodate natural sand redistribution and erosion over a 50-year lifespan.
