Lego isn't always the greatest communicator when new sets are announced, and sometimes it won't even tell you that new products are available to buy.
But normally, barring some leaks, announcements come through usual channels like press releases and social media.
The Architecture theme's representation of London's Trafalgar Square was a different story entirely.
We only know this set is coming because Lego announced there would be a special signing event on 27th April at the Leicester Square Lego store.
That announcement came from Facebook, of all places, and only included the bare minimum number of details.
For instance we know the set number is 21045, and that it has been designed by long-time Architecture designer Rok Zgalin Kobe.
