There is a delightful mix of historic architecture within the walls of Old Town. Most is called colonial built by the Spanish from the mid-16th through the 18th centuries. The Republican style was created during the era of Gran Colombia in the early 19th century and stretched through the 20th century. There is also a touch of European influences. Many of the buildings have been lovingly renovated while others are scared from serious disrepair. Most are adorned with lush vines and blooming flowers dangling from their second-story, wooden balconies. The results are charming to experience.
