Tla­co­tal­pan, a Span­ish colo­nial riv­er port on the Gulf coast of Mex­i­co, was found­ed in the mid-16th cen­tu­ry. It has pre­served its orig­i­nal urban fab­ric to a remark­able degree, with wide streets, colon­nad­ed hous­es in a pro­fu­sion of styles and colours, and many mature trees in the pub­lic open spaces and pri­vate gar­dens.
