The so-called “Great Temple” from the 7th century BC is the most important surviving pre-Christian sacred building in East Africa. The 14-metre-high structure is located in the northern highlands of Ethiopia in the village of Yeha and was probably severely damaged by fire around the middle of the 1st millennium BC. For decades it was considered to be in danger of collapsing, but its restoration has now been completed.

In order to preserve this cultural heritage, the Sanaa branch of the Orient Department of the DAI, together with the Ethiopian Antiquities Authority, has been carrying out extensive restoration work on the Yeha site since 2009, in addition to scientific research.

This included the installation of stainless steel support scaffolding to ensure the stability of the upper masonry shells. “The support structure was planned with millimetre precision using 3D laser data into the ancient structure and prefabricated by a steel construction company in Germany,” explains Dr. Iris Gerlach, head of the project. Other measures included the consolidation of the masonry: “An extremely lengthy process of closing cracks and doweling and gluing fragments together,” the archaeologist continues. The project is being supplemented with training components on site, with experts working closely with the local population. In particular, the time-consuming work of sealing cracks and missing parts was carried out with the help of local workers specially trained for these measures. All of these interventions served not only to preserve the building, but also to protect and maintain its cultural identity.

This historically important monument is now accessible again following the completion of the restoration work and its reopening in March.

Participation. At times, the term was already out of our ears, but it is currently gaining in importance again. Nevertheless, for many landscape architects, the demand for participation in the planning of public open spaces is still new. And unfamiliar. In the new Garten + Landschaft, we ask what constitutes good, consistent and uncompromising participation processes in planning and, above all, what landscape architects are doing to master their complexity.

What participation means
Participation projects have never been easy. With the dawn of the post-factual age, the challenges are increasing. Prejudices compete with facts. What is needed now are planners who are open to discussion, who communicate specialist content at eye level and are interested in everyone’s opinion. A status report.

The planner as activist?
An interjection by Agnes Förster, Studio | City | Region, Munich

Will without a way?
How is participation practiced? Specialist planning often views participation from a social science perspective. However, it is the legal situation that determines the opportunities for participation. Not everything is simply possible. Lawyer Marc Zeccola reports on the limits of direct democratic instruments in Germany.

Open heart surgery
The construction of Stuttgart 21 will free up an area of 85 hectares in the heart of the city. What will happen to it? The company Mediator manages the informal Rosenstein public participation project and shows how it is possible to organize city-wide participation processes constructively and cooperatively. We talked to the moderators about the process and the challenges it poses.

Playful participation
The Ruhr region is still undergoing structural change. In Herten, the former Schlägel und Eisen coal mine is being turned into a green industrial estate. Young people have been letting off steam in an obstacle course there since summer 2016. The special feature: they developed it themselves. We spoke to Nicola Jenik and Dagmar Lehmann from the Stadtkinder planning office on site about the project and their experiences of participating with children and young people.

Space from the test tube
In Oststadt in Karlsruhe, citizens, scientists and students are working together on the future of the district. An experiment in which everyone involved learns more about the challenges of urban planning.

The indomitable
Zebralog – the name of the office based in Berlin and Bonn refers to an animal with special characteristics: wild, stubborn and yet a herd animal. And this is also how the team works: in the field of cross-media participation, it uses the reach and low-threshold nature of the Internet to initiate dialog between specialist planning and citizens using unusual methods. At the same time, it always safeguards the equal opinions of a pluralistic society.

Grey as a trend color for exterior design

A trend color has emerged in the design of outdoor areas: Vandersanden has added new clinker brick models in grey to its already extensive range. This means that architects and local authorities will benefit from an even more diverse range of pavers in future.

The days when grey was considered old and boring are over – today, when it is natural and colorfast, it is absolutely on trend. The multifunctional color combines understatement with elegance and can be individually combined thanks to its numerous shades. In addition, gray represents both nature and the urban and is therefore also increasingly being used in the construction sector.
To meet this trend, Vandersanden offers a wide range of gray clinker bricks. Manufactured using the extruded and molded brick process, they not only impress with their modern shape, but also with different formats such as interlocking bricks, which enable different laying patterns. For an antique look, the clinker brick models are also available in a rumbled form. The different shades of gray of the new products are just as varied: While Gera (200 x 100 x 52 millimetres) comes in a nuanced grey, Jena (200 x 100 x 52 millimetres, also available as a format mix on request) scores with a grey-brown flamed look. Another new addition to the stock program is the grey-nuanced, muted Leipzig variety. All gray clinker brick models open up a wide range of design options and, depending on the selection and combination, always achieve a different effect. Further variants are already in development.

Indestructible markings

Pavers are also increasingly being used in road construction. In the form of directional markings, parking space markings or for the visualization of traffic islands and obstacles, they make a reliable contribution to increasing road safety. Thanks to its guaranteed color fastness, the natural product beats markings made with paint by far. The gray-white fired Carrara paving clinker provides a strong contrast to the dark road surface and is therefore ideal for use in public spaces.
