Moisture plays a key role in rock decay the built and natural environments. Rock-cut sites are particularly vulnerable to moisture-related weathering as they carved into outcrops do not have impermeable foundations or roofs retard flow of moisture. To characterise moisture dynamics its influence on rock-cut sites, we undertook monitoring campaign using non-destructive Microwave Measurement System (MMMS) at two monolithic churches Lalibela, Ethiopia. The results showed that walls were more...
This study concerns the eleven monolithic churches in Lalibela, northeastern Ethiopia, a UNESCO World Heritage Site and currently main pilgrimage site Ethiopia. In 2019, on initiative of Prime Minister, French authorities proposed their support management churches. To do so, Development Agency (AFD), collaboration with Ministry Europe Foreign Affairs Culture, granted feasibility to examine ways restoring, conserving, developing rock-hewn The objective conducted was produce preliminary...

<p>Weathering of rock-cut structures exposed to the environment is strongly influenced by fluctuations in climatic variables. Both macro and microclimate data are needed identify key weathering types rates likely affect a specific region. The aim this paper study micro conditions affecting churches Lalibela, Ethiopia determine how climate influences at site. Macro collected over 26-year period monitored on north, east, south west walls one Lalibela church complex (Bete Mariam)...
