Vizcaya Museum & Gardens was built in the early 20th century in the Coconut Grove area of Miami Beach. It is a fanciful architectural mixture of various Mediterranean Renaissance styles. Coquina, a soft local sedimentary rock was used for much of its construction. In recent years it has undergone a thorough and extensive restoration. Many notable building conservation firms including Conservation Solutions, Rosa Lowinger & Associates and Simpson Gumpertz & Heger have worked on the restoration. D/2 Biological Solution was used to remove the biological growth.
