Recreate a truly iconic landmark of Rome – the Trevi Fountain! Construct a detailed LEGO® brick model of the world-famous Trevi Fountain, the largest fountain in Rome.

This stunning Baroque monument carved from Travertine stone has been the backdrop for many classic movies, including Federico Fellini's La Dolce Vita. And, today, over 250 years later, the 49-meter-wide fountain still draws thousands of visitors to the small Trevi square.

Retailer reviews
Summarized retailer review data when available.
Great. The transparent light blue bricks that represent the water are a great addition to the entire collection. A must-have for every fan of LEGO Architecture.
A nice set where the details are very well represented. The booklet, like all architecture sets, contains interesting details about the fountain. Recommended for fans of architecture sets.
As an AFOL (Adult Fan Of Lego) and collector of Architecture sets, I can say that this one stands out. The 731 pieces are a lot for an Architecture set, and the book is very nice and of high quality, and the final result is superb. My personal favorite of this series - along with The Louvre. The price-to-value ratio is good here. I recommend it!
It's a fun thing, but it's quite easy for 12-year-olds. For a 9-year-old, it's definitely worth the money. There is also information in the instruction booklet. Unfortunately, this is in English. Overall, it's a super fun thing.
The LEGO Architecture Trevi Fountain contains many parts, so it guarantees many hours of building fun. The finished model also really looks like the Trevi Fountain. It is definitely as fun as visiting the fountain itself. Then, this is definitely a nice souvenir.
A pleasant activity on a rainy day. You can make it together with children...
