Reading the Signs of the Nature

A tour at the Fort San José de Bocachica on Tierrabomba Island in Cartagena de Indias (Colombia) invites critical reflection on the tangible threats of climate change in the contemporary world. Over the past 10 years, the rising sea level has threatened this authentic colonial-era military structure, increasing by 7 millimeters per year and placing the infrastructure at risk of partial or total flooding. The defense system is located directly on the rocky terrain of an islet in front of Tierrabomba Island and consists of seven vaults and an elevated platform with two alignments. The walls, made of lime coral stone, bear visible traces of colonial graffiti, offering a glimpse into the daily lives of its former inhabitants. These records also document the different vessels of the time, making this structure a testament to the maritime world in the colonial era ( Figure B8.1 ).
