This is the Castle display area at Lunaria Emporium where you can walk through them all. My first attempt at building in SecondLife 15 years ago was a castle and I never looked back. There three available for purchase in different styles and they all have multiple hidden chambers and passages to discover:

The Ceridwen castle, done in a fantasy/fairytale style in a silver and amethyst color palette with a special hidden room below

The Caerwyn Fortress complex, which is a massive, detailed fortress in the Norman / Celtic tradition with realistic 13th century textures. The fortress was inspired by the remains of Harlech Castle located in Harlech, Gwynedd, Wales

The Caerwyn Keep, designed with a smaller footprint in mind

A medieval covered stone bridge to match

There's also a partially finished Camelot Keep that I hope to get back to someday, but it is not currently available. All the castles are available on the Kitely Market here: https://www.kitely.com/market?cat=50600&store=13957705 and can be delivered directly to your inventory on your grid.

If you don't mind hypergridding, all venues are 20% off Kitely Market prices if you get them directly from my main store.
