The website has an interactive map
Did you know Plymouth's Christ the King Church was designed by the same man who is responsible for Battersea Power Station and the red telephone box?
Or that the city currently has most post-war listed buildings in the country, outside London?
These facts are all part of a project hoping to get people to "look again" at the city's architecture and buildings.
Plymouth: 20th century city is a web-based project which includes heritage walking trail maps and an audio guided tour to download.
The website also includes historical archive images from Plymouth and West Devon Record Office and various resources for the community and teachers.
"We want the 20th century architecture and built environment of Plymouth to be accessible and inspirational to all ages," said Marie Sellars of the Architecture Centre Devon and Cornwall.
The Church of Christ the King is Marie's favourite building
"It started as a conversation with architecture professor Jeremy Gould about the best way to get people noticing and appreciating Plymouth's 20th century architecture," explained Marie.
"We formulated the idea then we put in a bid to the Heritage Lottery Fund."
And although it's a web-based project there are lots of ways to access the information if you don't have a computer.
The family activity maps are available from a variety of venues including the museum and the Tourist Information Centre.
The site was designed and built by Plymouth-based media company, Onshore Media.
"We want it to be accessible to people of all ages and it was really good to get someone who knows Plymouth," said Marie.
"This was a fantastic project which allowed us to be innovative and inclusive in the telling of Plymouth's modern history," said Onshore's creative director, Robin Holland.
Plymouth Hoe's Naval Memorial is listed
So what does Marie hope people will get from using the site - which is also keen for people to send in their photographs to add to its collection of images of 20th century buildings in the city.
"What I hope is people will take another look at the buildings in Plymouth - something you might see everyday from the car can be very different when you see it as part of the walk."
And her favourite building?
"Christ The King," she replied, without hesitation.
"There is such a poignant story behind it, it was the last building Gilbert Scott designed, he was literally working on it from his deathbed.
"I love lots of buildings in the city but if I have to choose my favourite, then that would be the one."
