Isengard, also called Angrenost (‘Iron Fortress’) in Elvish, was located at the southern end of the Misty Mountains near the start of the River Isen. The Ring of Isengard referred to the circular stone wall that forms the outer defense.
Within the walls of Isengard, the ancient Númenóreans also built Orthanc ('Forked Height’ or ‘Mount Fang’), an indestructible stone tower. Isengard was granted to the White Wizard, Saruman, who lived within the stone tower until his treacherous betrayal of the races of Middle Earth during the Third Age and the War of the Ring.
We've recreated both Orthanc and the Ring of Isengard for you here, as it was in the days prior to Saruman's desecration of the forest and his excavation of the caves below the fortress. The mountain spring that fed the River Isen has been blocked to a mere trickle and though one of the outer walls is in disrepair (and needs refortification before it can be used by any park guests) the Tower of Orthanc still stands as a foreboding warning to any enemies. Guests are warned not to disturb the "Dueling Wizards" inside the tower... for the power of the Istari when fully revealed is truly frightening.
The scenario this week* includes a new scenery tab and 4 new paths. A few notes: The Orthanc scenery is designed to allow you to build it around a vertical ride. The center of the tower is hallow when arranged as designed. Of course, other designs can be accomplished as well (and even more will be possible when the Barad Dur/Mordor set is released, as the two sets are interechangeable with one another).
Given the sheer height of the tower when fully assembled, you need to place the base of the ride itself as low as possible on the landscape and begin stacking the tower scenery as low as possible (the highest I was able to go and complete the tower was with 1 layer of ground above the entrance height). Incidentally you can't place rides on the very bottom of the map, so you need to raise the land 1 level with the land tool first.
The paths used in the Ring of Isengard all have the same stone supports, however the railings are what vary: one has lamp posts on the railings, one has identical railings without lamp posts (used most effectively on stairs, as pictured; lamp posts glow blue on queue lines), one has no railings at all (full tile path) and the 4th has crenelations (also full tile). The lampposts can be a bit overwhelming if used everywhere, so we advise you spread them out by using the path with matching railings but without lampposts.
You could also use the path with crenelations for the Ring of Isengard itself, however I didn't think to make the path until after placing the crenelation fence pieces all the way around both sides of the entire wall (and after getting a sore wrist from doing it). Hindsight is 20/20 they say.
So grab your wizard's staff and enter the Tower of Orthanc... if you dare!

*The Moria scenery is not yet complete but I hope to release it sometime this weekend. We're trying to take our time with the scenery instead of rushing to get it done and as a result, will be releasing LOTR scenery into November as well. Remaining sets to be released: Moria, Lothlorien, Edoras, Barad Dur, Minas Tirith. Thanks for your patience.
