Saturday 9th of September marked a sad day for Doctor Who fans as the Doctor Who Experience closed its doors for the final time.

But a surprise proposal made the ending of the city landmark a truly magical event.

The sci-fi experience has been based at the heart of Cardiff Bay for the past five years, attracting thousands of fans to walk the same streets as the likes of Peter Capaldi, Matt Smith and David Tennant.

Tickets sold out for the last day of opening, with fans of the hit BBC television show taking part in a host of activities – including interactive exhibitions, and taking on a room full of terrifying Weeping Angels.

Daniel Green asked his girlfriend of three years, Annabel Hobbs, to marry him inside of the TARDIS.

The 26-year-old was instigated into the crazy fandom of Doctor Who by Annabel, who grew up watching the television show with her family.

“I am over the moon!” The 24-year-old said, “I am still really surprised. What has made it so emotional is the fact that the exhibition is closing today.

“This is definitely the top place that he could have proposed to me. He has done a good job.”

The Essex couple travelled down to see the exhibition for the first time in October 2016, after Annabel successfully managed to “bully” Daniel into going along with her.

“I wasn’t a big fan of the show before,” Daniel explained, “But seeing all of the props got me much more excited about it and now I enjoy it.

“The proposal has been planned for a long time and it has been so hard to keep it a secret, but I am relieved that she said yes and loves the ring.

“She’s very passionate about Doctor Who – that’s how I would describe it! She would like to think she’s an expert.”

So is a Doctor Who wedding now on the cards?

Annabel said: “We have had brief discussions about having some Doctor Who inspired decorations – but I don’t think I could convince Daniel to wear the attire!”

Other visitors came away from the experience feeling disappointed at the site’s closure.

One Twitter user, Sarah-Jane Pealing said: “This breaks my heart. I came [to the Doctor Who Experience] regularly, especially since I’ve based my Costume A-Level on Dr Who. Devastated. No chance of re-opening?”

Louise Burch added: “We loved the Dr Who Experience in Cardiff! Great exhibition with so much to see. Hope it finds a new home soon.”

Another user reached out to Cardiff Council for an explanation.

He said “@CardiffCouncil closing the Dr Who experience will be good for your tourism. Way to go. #sarcasm”.

The popular attraction has been phased out because its sub-lease from the Cardiff Council has drawn to an end. It closed officially at 5pm on Saturday, September 9.

The BBC’s official line at the moment is: “News of how we are planning further ways of taking Doctor Who directly to our audience, and how we are using the filming locations to continue the commercial presence of Doctor Who in Cardiff, will be communicated in due course.”

What’s On Reporter Josh Knapman, who is a huge Doctor Who fan, wrote a piece on why the closure is such a shame for Cardiff.

He said: “The experience offered a tourist destination to the city that fans far and wide would come to see, especially after Matt Smith’s run as the Doctor seemed to increase the US audience numbers.

“It really put Cardiff – and Wales on the map – and had fans booking hotel rooms, spending money in our shops, eating in our restaurants, visiting other attractions and generally spreading the word about Cardiff being a great tourist destination.”

Jodie Whittaker was recently announced as the thirteenth, and first female, Doctor .
