Conservation projects by region

There are over sixty projects on more than forty sites.

The projects and the reports described here were ordered by various groups such as: Authorities of the Nature and National Parks, Antiquities, Runoff water Drainage; Municipalities of Jerusalem, Beer Sheva, Akko; Universities and more.

Each project is briefly described and the conservation tasks are listed. The majority of the projects described here have been carried out while a few still remain in the planning stage. As of today, about 10 reports are presented in English (20 reports in Hebrew). Before long, more reports will be translated and reports that were done before the digital age will be transferred to Internet format.

Special acknowledgement is given to the Nature and Parks Authority for placing the conservation of heritage sites at the head of their priorities. While enduring the lack of funds and trained workers, the onsite staff of the Authority is making an outstanding, efficient and professional effort in conserving the national archaeological parks which are in a constant decay process. In the past decade, the Nature and Parks Authority took giant steps forward to acquire independence in conservation and maintenance needed for the professional care of the Nation’s heritage sites and raising the public awareness to the issues. This is similar to what was done successfully over 20 years ago with the campaign for the survival of plants and wildlife.

Most important is that all these projects were performed by the best conservators, planners, archaeologists and workers. They are dedicated to the conservation of Israel’s heritage sites; to them we are most grateful.

Throughout the process, incredible challenges and problems arose and confronted but in the end the ruins were transformed into stable and maintained sites, presenting their secrets and heritage for generations.

This challenge requires never-ending creativity, efficiency, hard work and the courage to dare and as always who dares wins!

Sites of the Perfume Road

The Saharonim Caravansary

Conservation in the Land of Genesis:

This is the first of the Perfume Road sites that was transformed, by conservation, from a complete ruin to a picturesque site in the heart of Makhtesh Ramon. The site is built with two types of very unstable, problematic stones: gypsum stone and clay rich "questa" stone. In addition, there was a need to excavate the large courtyard and the area in front of the gate in order to sense the size and original use of this caravansary.

Main conservation topics: damaged stone, plaster, wall reconstruction for conservation and presentation, landscape conservation.

Moa caravansary

The caravansary, fortress, and water pool

The conservation project included restoring heavy stone lintels to their original location, conservation of the oil-press and excavation and conservation of the large pool near the blocked up spring. At the end of the project, there was an earthquake in the region and the ancient Moa spring opened and began to flow. In a mysterious way the pool was filled by the spring via an underground method. This was a great surprise. No one imagined that this could ever happen again. .

Main conservation topics: walls, entrances, installations, plasters.

Makhmal Ascent Fortress

On the edge of Makhtesh Ramon rim.

The small fortress stands on top of the ancient Makhmal camel ascent overlooking the whole of Makhtesh (crater) Ramon. After the excavation in the 1960's the fortress was left to deteriorate into complete ruins. The conservation work at Makhmal was a prerequisite to nominate all the sites of the Perfume Road as a World Heritage Site. See detailed report

Midras Ruins

The reconstruction of a tomb

Midras ruins have an amazing cave/built tomb that, sadly, was destroyed by ultra-religious vandalism. The cave was, fortunately, documented and measured by architect Giora Solar, before it was vandalized. The tomb was build with massive stones in a relatively small area that is difficult to maneuver in. This poises a challenge to the conservation efforts. Currently, the conservation plan has been prepared. The work has yet to be implemented.

In the early 1960's, the elaborate system of pools and canals for gathering the flood waters of the Qumeran Wadi was excavated and stabilized. The pools are dug into the salt-rich soil. The white cement, which was used as a stabilizing material, severely damaged the original plaster system. A difficult and complicated part of the project was taking apart the white cement. The conservation project of Qumeran was a unique, professional challenge and served as a milestone in the development of lime and earth plaster conservation techniques.

See detailed report

Main conservation topics: lime plaster, earth plaster, earth bricks, and installations.

Negev and Arava Desert sites

Historical Beer-Sheba

Model for soft-stone conservation

As part of reconstructing the Governor's house, a model was created based on survey, documentation and analysis of the present state of conservation. This resulted in a suitable plan for dealing with the severe deterioration of the soft stone in Historical Beer-Sheba. Replacing original stones with modern stones was the last course of action recommended.

See detailed report

Main conversation topics: soft stone


Training excavation

The excavation by the Ben-Gurion University continued unearthing the central church and the nearby theatre. Due to poor conservation state of the main construction stone – soft chalk limestone – there was a need to conserve during the excavation including partial reburial of the excavations and runoff water management during rainy season.

Main conservation topics: conservation during excavation- SOS treatments.


The Eastern Church

This church, shown in the famous Byzantine Madaba map, was destroyed when the Muslims conquered the Negev. As of today the Apsis rooms' floor stones and the Baptistery have been conserved. In addition, the large central mosaic floor, which was in one of the worst conservation states the country, received long awaited treatment. The floor, reburied over 15 years ago due to its problematic condition, was uncovered and full and conclusive conservation treatment and stabilization was performed.

See detailed report:
