Lady of Rohan - a great fansite by Tigerlily, with tons of goodies, including all the awesome pictures and multimedia files my lil' site lacks.
White Lady of Rohan - a very pretty tribute with lots of information and plenty of links.
Emyn Arnen - Maggie's gorgeous Eowyn/Faramir tribute site with lots of information, art, film information, and links. Also check out the Emyn Arnen Fanfiction Archive for some great stories.
A Shadow and a Thought - a lovely fansite devoted to the unrequited (and very interesting) Aragorn/Eowyn relationship.
Parma Eruseen - a fabulous forum where I moderate (and also fawn over Eowyn and Faramir). Home to some of the most enthusiastic LotR fans around!
Dernhelm - the fanlisting for Eowyn's alter ego as a knight of the Rohirrim.
The Tolkien Trail - Ben's fabulous site, built for endurance, with a tour of Middle Earth. A literature-based site, but it's been around awhile now and deserves a visit.
Alison's costume page - with pictures and descriptions of all the cool outfits Miranda Otto wears in TTT.
Women & the Sea - from the Mariner's Museum, includes sections on women passing as sailors, mermaids, and myth.
