Heritage visitor centres have noticed a slight change in their demographic of late...
Usually at about lunchtime a few people wander in, phones held up in front of them, looking around. Then they turn away and leave again. Score one for the footfall target.
Pokemon Go, which launched in the UK a fortnight ago has made heritage attractions and places of interest into Pokestops, meaning the younger generations, which are statistically much harder to reach in the heritage tourism industry, are suddenly searching them out.
Pokestops are a place to go to top up on Pokeballs (to catch your Pokemon) as well as other gifts. They also attract Pokemon, especially if they are highlighted.
From a PR point of view it's great. The attractions are gaining footfall and young people are engaging with them. It's giving them something new to promote and talk about.
Susanna Plummer from Doddington Hall in rural Lincolnshire said: "We have indeed found that we have been visited by Pokemon at Doddington Hall, hiding outside our Farm Shop, Estate Office, Gardens and around the Estate.
"We are certainly hoping that this will bring in a younger audience to the Estate over the summer holidays-especially with our Sculpture Exhibition being open daily from 30 July - 11 September. We've already noticed young families out and about together, giggling working as a team and having a great time."
But the challenge is retaining visitors once they're there. How can heritage attractions make Pokemon trainers stay longer?
Sacrewell, near Peterborough, is a pay to enter attraction. They're an agricultural education charity and the Pokestop is inside the centre.
So they've introduced a Pokestop entry fee for those who want to top up on Pokeballs and go. All they have to do is pay a donation to the charity, but if they want to stay and catch Pokemon (especially if the centre is highlighted and attracting more Pokemon at the time), they have to pay full admission.
So not only are trainers catching and shopping, they're supporting charity too.
General Manager Debbie Queen said: "As soon as we found out the Shepherd's Hut at Sacrewell was a Pokestop we knew we had to find a way to encourage people to stop at the centre and engage with us, especially if they're on a long journey as we're just off the A1/A47.
"There's free entry to our gift shop and cafe, so we're hoping once they're here they'll stop for a bite to eat or to explore the centre in full. We've got a busy summer ahead with summer fun activities every day and we're putting on a lot of events that'll attract Pokemon Go families."
Oakham Castle on the other hand is a free to enter attraction. Their aim is to get people to stay on site a bit longer and make the most of the Castle (which is still a bailey with the Great Hall in the centre) .
So they've started putting out teas, coffees and games to play to get people to stay. There's a small donation box for drinks which go back into the Castle coffers.
While queuing for return tickets to Aladdin the Musical at the Prince Edward Theatre in London last weekend, I logged in to see what was going on around me. There are a lot of Pokestops in the West End and even as I stood still I caught six Pokemon. It killed the time and kept us amused for an hour or so.
I'm interested to know how other tourist attractions are catching on to the Pokemon Go phenomenon. Have you seen any innovative ways attractions are encouraging Pokemon trainers? If so, get in touch or use #InspiringBritain in your photos.
