Description from LEGO.com

A fun boat-themed gift idea for travel- and history-lovers

Read the full description

Honor the meticulous craftsmanship involved in building a classic river steamboat with this LEGO® Ideas model kit for adults (21356). This minifigure-scale display model captures the authentic details of a steamboat that has been refurbished for entertainment tours, and makes wonderful nautical decor for the home or office. Move the boat on a surface to activate the paddle connected to the ’steam’ engine, turn the ship’s wheel in the pilothouse (or the knob outside) to activate the rudder, raise/rotate the boarding stages and drop the anchor. Explore the pilothouse, crew cabin and bathroom on the texas deck; the music stage and restaurant on the main deck; and the boiler deck, which features a kitchen and a steam engine museum that showcases a LEGO working piston, Watt steam engine and more. Find step-by-step building instructions in the box or on the LEGO Builder app. This collectible set makes a super gift idea for men, women and any boat travel enthusiasts or history-lovers. Contains 4,090 pieces.
