Construction on the castle began in 1868 and was completed in 1874. In contradiction to this the current owner of the castle says it only took 3 years. Interestingly Godwin, prior to any construction, visited and noted key details of other castles around Ireland. In particular he looked at the construction of roofs/porches and the joining of stonework.
The castle possesses many notable features of your average castle. These include Slit windows, a tower, pointed arches, mullions, transoms, spiral staircase(interior) and most notably a carved limestone fireplace( this is not there anymore). It is no surprise that close to all these features were made from limestone as this was in plentiful supply around the local area.
The roof was a hipped limestone roof and below is a picture of this before it was knocked in.
The stone itself was sourced from Foynes and from the outer fascade is made up with this stone. The interior is made of a red brick that was probably sourced locally too. This done by Godwin to try counter-act the dampness. Leaving a 2 inch cavity from the stonework he made a line of bricks which can still be seen today.
You can also see in some pictures where the joists ran across for the individual floors which just highlights the comparisons between past and modern techniques.
Subsequently around the time of its completion many architects from around Europe came to analyse the design and construction of the building. Many castles in Germany have been designed based on Dromore.
The strange thing about this castle was that it was built based on the gothic era yet it was long after the gothic era had ended. Thus features such as arched frames, arched windows, spiral staircases and defense features such as murder holes, turrets and slit windows were all implemented into the castle.
