图书馆位于Ciudadela西北天井的北侧的两个海湾中。它是为了放置安东尼奥-卡斯特罗-莱尔的个人图书馆而设计的，它被投影成一个透明的区域，书柜被贴在墙上，达到全高，这些深色木材的垂直元素与浅色木材和半透明玻璃的水平平面（地板）形成对比，白色的家具也是如此。尽管空间是开放的，但人们可以区分出四个不同的区域：接待区、团队工作区、个人阅读区和研究区。
每个部分的模块化解决方案响应了原有建筑的加泰罗尼亚天花板上的金属结构梁的放置，走廊通过轻薄的不锈钢圆盘悬挂在这些元素上。栏杆是连续的，并且在方向和末端的变化上有衔接。每个书柜的边缘都有一条来自利德的连续带子，照亮了每本书，它们似乎在空间中振动。简单和模块化的书柜与铁艺栏杆和专为这个空间设计的桌椅的特殊细节相得益彰。从工业设计到建筑的整体解决方案参考了卡斯特罗-莱尔在其位于科约阿坎的家中的个人图书馆。其结果是一个容易被视觉理解的，对游客来说是家的感觉。
The library located in two bays at the north side of the north-west patio at the Ciudadela. It was created to place the Antonio Castro Leal’s personal library, it was projected a transparent area in which the bookcases are attached on the walls to full height, these vertical elements in dark wood make the contrast with horizontal planes (floors) in light wood and translucent glass, so too the furniture in white. Despite the open space, one can distinguish four different areas: the reception, the teamwork area, personal reading area and the research area.
The modular solution for each component responds to the placement of structural metal beams on the Catalan ceiling of the original building and the hallways are suspended from these elements by a light and thin stainless steel rounds. The railings are continuous and articulated in the changes of direction and ends. Each bookcase panel has on its edge a continuous band from leeds that illuminates each book and they seem as vibrate in space. The simple and modular bookcases complemented with especial details of ironwork railings and the tables and chairs designed specifically for this space. An integral solution from industrial design to architecture took as reference the Castro Leal’s personal library at his home at Coyoacan. The result is an easily visual comprehension and homely to visitors.
