This is a standard concentric fortification unit with two curtain walls of about two and five meters in height respectively. All walls including that of the fort proper feature large battlements perfect for climbing up and getting an advantageous position to make you next movement. There is an obvious entrance on the Southern parts of the structure which feature a rising wall surrounding the stairs; this would make for an easy climb to the top so I will instead focus on the strategy on climbing the more difficult areas of the fort. As is often the case, don't let the term concentric fool you when it comes to defensive structures. In fact this is an octogonal design. This offers a unique challenge many don't get to encounter as often as say walls with 90 degree and 270 degree corners, inside and out. 135 degree and 225 degree corners feel novel every time. The bailey within the enciente is often clear, but I have seen it filled with fence posts, chairs, and the like from time to time. The inner bailey has only ever been devoid of obstacles. Thus, you'll be relying a lot on wall tech alone. After the rather easy scramble up the first wall, a leap from the top of the battlement should set you up nicely to grab the next wall (both Bailey's can't be any wider than two meters). From the top of the next one a decision has to be made. Taller and/or stronger climbers can go for the rounded ridge that encircles the tower just below the parapet while the athletically inclined would benefit from a wall walk using a running and angled jump from the middle wall, making use of the multiple footholds and crenels of this structure. This is the last obstacle to the top as nothing more than a vault will ensure your ability to sync up and update your map. Overall I give it six Bayeks of Siwa out of a possible ten Bayeks of Siwa for the climb, and five arbitrary Google-stars.
