Analysis of information sources in references of the Wikipedia article "Seashell" in English language version.
Brittle buildings made of "shellcrete," a seashell-cement mix applied over logs, are risky to move.
Many impressive old homes and public buildings, as well as more mundane structures such as cisterns and curbs, were constructed of shellcrete bricks in Corpus Christi, Galveston, and other cities along the coast. However, very few exist today.
