Limerick, like many other cities in Ireland, boasts a rich history of remarkable architecture. A document from 1574, prepared for the Spanish ambassador, provides a detailed description of the city's wealth and architectural features:
"Limerick is more formidable and aesthetically superior to all other cities in Ireland, with robust walls made of hewn marble. The city is accessible only by stone bridges, one of which features 14 arches, while the other has 8. The majority of the houses are constructed from square blocks of black marble, built in the form of towers and fortresses."
Several notable examples of this architectural heritage remain, including the 800-year-old St. Mary's Cathedral and King John's Castle.
