LEGO Harry Potter 76420 Triwizard Tournament: The Black Lake

The Triwizard Tournament: The Black Lake and the Hogwarts Castle Boathouse are both part of the LEGO Harry Potter series and feature Harry Potter as a character, but they have some distinct differences. The Black Lake was released in 2022 and includes 349 pieces, while the Castle Boathouse is a slightly newer 2023 release with one additional piece, totaling 350. Both sets share the Fantasy and Movie Characters themes, but the Boathouse also includes a Building theme, which might appeal to those interested in architectural designs. From a collector's perspective, both sets are nearly identical in terms of the number of pieces, making the choice largely dependent on individual theme preference and the novelty of owning a newer set. Ultimately, the decision may rest on whether the unique features of the Boathouse's themes align more closely with a buyer's interests or collection goals.
