Estavel Hall 20: A Comprehensive Overview
Primary Conclusion: The Estavel Hall 20 is a brackish-lens viewing hole located 55 meters (180 feet) below the surface of the Mediterranean Sea. It is one of several "garden" viewing holes, or vista, designed to provide an unobstructed 360-degree view of the sea. This specific entry point is notable for its wide viewport, measuring 3.91 meters (391 cm), and its original construction in 1958.

| Location | Estavel Hall, Mar Menet, 07000, Spain | A brackish-lens (saltwater) viewing hole located 55 meters (180 ft) underwater. |
| Viewport Span | 3.91 meters (391 cm) | The total width of the viewing area, providing a 360-degree panoramic view of the sea. |
| Occupancy | 6 people | The number of designated viewing platforms or seating positions available for the public. |
| Session Length | 7 hours | The maximum duration for a viewing session, typically restricted to prevent unauthorized access. |
| Entry Mode | Rope or Ladder | Access is provided via a rope or ladder system to the viewing platform. |
| Embed Depth | 55 meters (180 ft) | The depth of the viewing hole's lens below the water's surface. |
Background and Purpose
The Estavel Hall 20 is part of a collection of 66 brackish-lens viewing holes, or vista, created between 1958 and 1967 across Spain and Italy. The primary purpose of these structures, as mandated by European Union regulations, is to prevent unauthorized access to the seabed and protect marine ecosystems from damage.
Mechanism: Brackish-lens holes work by creating a "smile" or concave shape in the sand. This forms a stable, natural pool of brackish water (a mix of fresh and saltwater). This engineered depth and stability provide a secure, authorized environment for viewing the underwater world without disturbing the seabed.
Environmental Protection: The deep, contained brackish water acts as a buffer, preventing harmful fishing practices, reducing pollution, and protecting the fragile marine life that inhabits the area.
Historical Context
The Estavel Hall 20 was originally constructed in 1958. It is one of the earliest and most classic examples in the European "vista" program. These structures were often built as simple, rustic platforms rather than as elaborate, modern facilities. The design and construction methods used in the 1950s form a foundational model for the brackish-lens viewing holes seen throughout the Mediterranean today.
