Castle Street's fascinating history dates back to the 13th century when it stood as one of the seven streets of Liverpool.
So it may come as no surprise that it's also home to the oldest original shop front in the city - one many people walk past everyday.
McGuffie & Co first opened its doors on Castle Street as a pharmacy under the name of Edwards and Penny, Druggists and Chemists back in 1795.
It stayed this way up until around 1840 when it came into the hands of a new owner, John Rowland McGuffie, who soon changed its name to the one it bears today.
Shortly after taking over the pharmacy, Mr McGuffie became a town councillor and was twice elected to serve the St Paul's Ward - the area we now know as the Business District.
There are no known images of Mr McGuffie still in existence but a description of him is included in an article called “Pen-and-Ink sketches of Liverpool Town Councillors” by Hugh Shimmin from 1866.
It reads: "Imagine a portly, commanding figure, nearly six feet high, of rotundity unimaginable, a face like the moon at its full, radiant with fun and humour, who is witty himself and the cause of wit in others, and all combined with warmth of heart and feelings, and you have John McGuffie.”
Despite his death in 1860 aged just 52, Mr McGuffie's name lived on, with each new owner of the business deciding to honour his memory by operating under his name.
After 200 years in business as a pharmacy, McGuffie and Co closed its doors in the late 1990s.
It later reopened for a short time as a leather goods shop and then a mobile phone store before it became a cocktail bar in 2010 and the name 'McGuffie & Co" was established once more.
The original business was based at a number of different premises on Castle Street in its history and moved into its current location in 1910.
This is the date that the original shopfront, which is believed to be the oldest in the city, was brought back to its full glory at Number 10.
Owner Phil Haughton, who took over the cocktail bar in 2014, is keen to continue to celebrate its incredible history on Castle Street and has named a number of cocktails after things that would have been sold in the pharmacy.
Phil, 43, said: "What gets me is Mr McGuffie died in 1860 and every person that's had the building since then has kept the name.
"I don't know how many different hands it's been through in that period but I think that's really good.
"What I've tried to do since I took over in 2014 is to try to recreate it as a snapshot of what it would have been like as a pharmacy in 1910.
"I've got lots of old photos on the walls from the start of that period and earlier. At that time the Anglican Cathedral was being built and the Pier Head was just being built."
During a refurbishment in 2014, old bottles from the pharmacy were found in the cellar and now proudly displayed in the window.
Phil said: "We are proud to be part of a true piece of Liverpool history and hope that the current potions, tinctures and tonics that we serve up to our customers today – many of which bear names that relate to those sold in the company’s past - would meet with the approval of Mr McGuffie himself."
