"The works fig 21.01 Calle Ignacio Manuel Altamirano 268 and fig 21.02 Calle Jose Azueta 271 are 1:25 models of the inside surfaces of two basements in Mexicali. These two basements are presented as parts of an extensive tunnel system built under Mexicali/Calexico at the beginning of the 20th century, when the population of the city swelled with Chinese and Chinese-Mexican laborers. With the rebuilding of the basements came a performative aspect, a certain intimacy with the space. This provided an alternative access to this history based solely in form, the building systems, and architectonic decisions. How does architecture hold memory, what is the presentation of history, and for whose gaze? The access to this history is shaped by those who would own the knowledge of the tunnel systems. The spectacle becomes the history, and perhaps contrary to intentions, renders the history opaque and impenetrable." — Yeni Mao
