## Description

Capture the essence of a historical London landmark with the LEGO Architecture 21045 Trafalgar Square set. Named in honor of Lord Horatio Nelson following his 1805 naval victory over Napoleon, the square has since become a popular tourist attraction and preferred location for political and community gatherings. This detailed LEGO interpretation depicts the domed National Gallery complete with columned facade, Nelson’s Column flanked by 4 lions, the square’s famous fountains and 4 sculpture plinths. The sections at the rear of the National Gallery structure can be removed for access to a detailed interior with brick-built statue and paintings. Tree-lined borders, ornate lampposts, 2 London buses, 2 black cabs and a tiled baseplate depicting the square and surrounding roads complete the model. Finished with a decorative nameplate, this LEGO Architecture set delivers a highly satisfying building experience to all with an interest in architecture, travel, history and design, and makes a truly iconic centerpiece for the home or office.

Review: My Second Favorite LEGO Architecture Set - I own and have built a number of LEGO Architecture Sets including the San Francisco Skyline, the New York Skyline, Buckingham Palace, Big Ben, the United Nations, the U.S. Capitol, the White House and the most recent version of LEGO's Empire State Building. The LEGO Architecture 21045 Trafalgar Square Building Kit stands out as one of the best. In fact, if it weren't for the outstanding LEGO Empire State Building (21046), the Trafalgar Square would be my favorite LEGO Architecture Set. The set includes National Gallery, Nelson’s Column, two London buses, two black cabs. four lions statues, two fountains, four sculpture plinths, ten trees, six lampposts, realistic steps, and an impressively curved road. All this this is created from 1,190 individual brick pieces. The set was a fun build. I completed it in a day and thoroughly enjoyed the build. The set is amazing to look at once completed. At 4” (12cm) high, 9” (24cm) wide and 7” (20cm) deep it's larger than many of the other LEGO Architecture sets. LEGO has designed a very creative use of LEGO blocks in several places. For example, there are "displays" inside of the National Gallery. Instead of having to pull the roof off of the top as is the case with, say, the LEGO U.S. Capitol Building, there are three easy to remove and replace doors on the back of the National Gallery. Simply pull them off by the handles and take a peak inside. This is a much better and a far more realistic way to "look inside" the building than a roof pull. The set, of course, isn't a perfect replica of Trafalgar Square. The National Gallery has been shortened. However, if it hadn't been the model would have been gigantic and perhaps unwieldy. The lion statues don't look realistic. The cabs and buses suggest but don't really look like the real thing. The peaked roof over the National Gallery’s front doesn't quite fit properly Finally, the trees are a bit phony looking and the top of the trees are difficult to construct. This is because LEGO has decided to place a 1×1 Plate, Round Brick on the 2×2 Plate, Round w/ Axle circular brick that makes up the top of the tree. The pieces aren't really made to go together in this manner. This makes it hard to push the round brick on to the tree's top piece. After some experimentation, I found that I could use the tree trunk piece as a tool to insert the 1×1 Plate, Round Brick onto the top of the tree. All of these are issues, albeit minor, with the LEGO Architecture 21045 Trafalgar Square Building Kit. Still, we can forgive most of these issues as they really don't distract from the overall beauty of the outstanding finished model

### ⭐⭐⭐⭐⭐ Perfect material
*by V***E on December 3, 2025*

Excellent piece well designed

### ⭐⭐⭐⭐⭐ I have a problem I'm addicted to Lego sets 😍🤯
*by A***N on August 12, 2019*

This Trafalgar lego set is awesome if you like lego's and you over the age of 20 or even your late teens then you will like this. I ordered it this last Friday, got it on Saturday and finished it on Sunday the only real problem I had was that the two pieces that make the front of the roof don't lie flush with each other (see last picture)like it show's on the box but other than that I got exactly what I paid for and had a great time building this Lego set .One thing to know this is pricey it's 79.99 but when tax is added it comes to 86.59 almost 90$ but other than that this is an awesome Lego set. You can bet I'll be getting more in the future
