What is the Barad-dûr fortress?

The Barad-dûr is the home of the Sauron, the antagonist in J. R. R. Tolkien's "The Lord of the Rings" book and film series. The tower was sustained by dark magic and deemed the greatest fortress in Middle-earth. In the 2001 film "The Lord of the Rings: The Fellowship of the Ring," Sauron was voiced by actor Sala Baker.

Sauron, also known as "the Dark Lord Sauron," created the One Ring, a central plot element in "The Lord of the Rings" series. Frodo Baggins, played by actor Elijah Wood, goes on a quest to destroy the One Ring and save Middle-earth in "The Lord of the Rings: The Fellowship of the Ring."

What is included in the Barad-dûr Lego set?

Included in the Barad-dûr set is a throne room containing a compartment that opens to reveal a map, and a ladder on the top floor of the tower that can be moved from left to right, according to the Lego Group's release.

At the highest point of the tower "lies the Eye of Sauron" which rotates in various directions and features a light brick that makes the eye glow, the toy company said. The Eye of Sauron was a symbol of the dark lord that Frodo Baggins perceived while carrying the One Ring during the series.

In addition to all the dark tower's features, the set will come with 10 mini-figures, including Sauron, Mouth of Sauron, Orc, Frodo, Sam, Gollum and Gothmog, the Lego Group said.

The entire build is split into four main sections, with the tower section being fully modular, according to the Lego Group's release. If a Lego fan bought more than one Barad-dûr set, they could stack the tower sections on top of one another to "build a taller tower," the toy company said.
