Where better to ‘shellebrate’ the first National Seashell Day on June 20th than a property that is literally built on shells – the Mound House? Without easy access to stone, the Calusa Indians, who lived on our shores 2,000 years ago and built the mound that sits below the Mound House, used shells as tools, weapons and building material. Museum staff presented several special programs Monday focused on the role of shells in the culture of the Calusa. Additional programs are offered weekly. See the Around & About section of the Sand Paper for a list of upcoming events or visit moundhouse.org.
