Herein disclosed are a generally arched, prefabricated PC shelter structure, a pair of unit half plates for forming an arched unit together to construct the arched shelter structure when a plurality of pairs are fastened together side by side, and a process for prefabricating the paired unit half plates together. The shelter structure is constructed of a plurality of pairs of unit half plates prefabricated of highly strong concrete. Any paired two of the unit half plates are peripherally curved to form the generally arched unit together when they are assembled to have their tops abutting against each other. Peripherally fastening means is incorporated for peripherally fastening the abutting tops of the paired two unit half plates together to form the generally arched unit. Transversely fastening means is also incorporated for transversely fastening a plurality of generally arched units, which are arranged side by side, together to construct the generally arched PC shelter structure. The legs of the paired two unit half plates are anchored at the foundations of the field.
