From 2011 to 2015, the Ephorate of Antiquities of Messenia (formerly the 38th Ephorate of Prehistoric and Classical Antiquities) and the Directorate for the Study and Execution of Museum and Cultural Building Works of the Hellenic Ministry of Culture and Sports implemented the following projects:

1. “Protection and Enhancement of the Archaeological Site of the Palace of Nestor on the Hill of Ano Englianos, Chora, Messenia” (budget: €450,000), and

2. “Construction of a New Protective Shelter over the Palace of Nestor at Ano Englianos, Regional Unit of Messenia” (budget: €2,068,400).

Both projects were included under Priority Axis 08 – Sustainable Development and Quality of Life in the Peloponnese of the Operational Programme “Western Greece – Peloponnese – Ionian Islands 2007–2013”, co-financed by Greece and the European Regional Development Fund (ERDF).

The metal protective shelter originally installed over the monument by the Greek Archaeological Service in 1961, covering 2,300 m² and supported by 47 dexion-type columns, had suffered extensive deterioration.

It was replaced by a modern steel structure, which now provides integrated protection for the main palace complex, covering an area of 3,185 m².
The new arched roof, with a total span of 51.5 m and a radius of curvature of 84.88 m, is supported by only 16 columns, evenly distributed along its two long sides.

Suspended metal walkways form a visitor circulation network above the monument, while a special elevator ensures accessibility for people with disabilities (PWDs).

During the replacement works, archaeological excavation and documentation were carried out. For the enhanced protection of the monument, its fragile sections were enclosed in wooden casings, the interior spaces were protected with inert materials, and the entire central building was covered with a continuous wooden floor.

New visitor, information, rest, sanitation, and safety infrastructures, with particular attention to the needs of people with disabilities, now ensure high levels of functionality for the archaeological site and offer visitors a unique experience of exploring the Mycenaean past of Messenia.
