If you are keen on exploring local historical sites on your vacations, the Plas Mawr townhouse in the town of Conwy in Wales is a great place to visit. Originally built in the 16th century as a residential building, the Plas Mawr was subsequently restored as a tourist attraction. What makes the Plas Mawr a must visit is the elegant Elizabethan façade of its architecture which has been preserved excellently. On a tour of the house you will also be able to see the elements of the local Welsh and Renaissance influences in the design and interiors which also feature royal arms from several noble families of the area. An excellent place to visit on a casual day.
