This wonderful footage shows how one of Chester's most famous landmarks would have looked centuries ago.
The digital reconstruction rewinds the clock to the 17th century and paints a picture of Chester Castle in its former glory.
Martin Moss, of Chester, used video gaming technology to digitally rebuild the fortress and bring it back to life.
Martin, who has also produced reconstructions of the castles at Flint and Ewloe, said: “It is just a hobby of mine that I do in my spare time in the evenings, but if people watch them and get some joy from them that’s really good.
“I chose Flint and Ewloe as I live in Chester but have a lot of family near those areas and just thought it would be interesting to model how they would have looked back in the day.
“I have to do a lot of research online for each project about what they would have looked like and can spend about five to six weeks just on the research.
“It then takes me about three to four weeks to actually build them – about 12 hours.”
The architect Thomas Harrison remodelled much of the castle in the late 18th century, but paintings and sketches of its medieval appearance and layout still exist.
Martin says he drew his source info from an artist named Moses Griffith, who painted the castle from several angles at a time when much of the medieval structure still remained.

It was the Saxons who first erected a fortified base on the strategically important site, in 907AD. Over the centuries, it was rebuilt by the Normans and damaged during the English Civil War before being developed by Harrison in the 18th century into something close to what we see there today.
Chester Crown Court stands within the site Harrison redesigned. In Martin's video, other well-known nearby landmarks like the Old Dee Bridge and the church of St Mary-on-the-Hill can be seen.
