Vernacular architecture is an important part of a region's culture. It reflects the region's history, religion, surroundings, climatic conditions and mentality. As a communal good, it evolved over hundreds of years and changed with the residents. To understand this multifaceted construct in its entirety, methods from building research, cultural- and social anthropology and cinematic documentation were used. The thesis 'Between, Rock, Sea & Palm ' researching vernacular architecture on Qeshm Island' concentrates on this, till now, barely researched topic. Qeshm is the biggest island in the persian Gulf and located at a militarily important location at the mouth of the Gulf. This often put it at the centre for the struggle for dominance in the Gulf. To ensure a comprehensive view and reach a broader audience, the thesis is split into a practical part in the form of a documentary film and a theoretical written part that constitutes the scientific base of the movie. The general topics covered by this thesis are approaches and methods in building research, and the current state of the vernacular architecture on the island. These topics are covered with reference to a research project by the TU Wien in 2015, which was documented on film, and the existing literature. A specific area of interest for this thesis is the stone-loam architecture found in the fishing villages on Qeshm's coast, including their village structure, the courtyard type, the water reservoirs and the palm garden houses. Insight into the island's history and factors that have influenced life and architecture on the island are given. These include historical events such as the slave trade, the advent of Islam in the Gulf, access to new building materials and techniques through trade, tribal movement throughout the Gulf, as well as modern influences through globalisation, climate change and political intervention such as Geoparks and the Free Zones. Globally, a striving towards an international style, that often disregards way of life and climatic condition and endangers cultural heritage, can be seen. More so now than ever, given the importance of sustainability and the scarcity of resources, , a lot can be learned from vernacular architecture.
