The people of the Colombian capital saw themselves losing hope in the idea of in-person Easter celebrations as the prospects of a third wave of Covid-19 cases intensified. Colombian culture at large is fundamentally religious, and social distancing measures in response to the pandemic have affected the religious community in particular with the prohibition of large congregations. Believers have seen themselves disconnected from their faith and churches have gone into economic crisis. 
  
As Easter approached, architecture firm Colab-19 contacted the Archdioceses of Bogotá to donate a temporary chapel that could facilitate bio-secure in-person Easter celebrations. The Archdioceses responded with great interest and put the designers in touch with the “Santa Maria de la Alhambra” Church, a community that´s experienced particularly negative repercussions during the pandemic. Covid 19 provoked an economic crisis that made the church unable to host mass gatherings. This congregation needed a space where Easter celebrations could take place in accordance to social distancing protocols.  

Colab 19 built on their knowledge of ephemeral architecture made from pre-existing infrastructures in pursuit of a model that could go beyond the vertical framework of scaffolding. They developed a model that could use horizontal formworks as the main compositional element for the chapel´s design. This system has habitability qualities similar to those of scaffolding, but it´s better suited for rapid horizontal growth that leads to a “Column Forrest” aesthetic.

The designers considered similarities between this horizontal system and the architectural language present in Christian architecture, and arrived to a “Greek Cross” typology that stands out as a landmark within the urban iconography of Bogotá. 

Colab 19 decided on a final design and contacted the Colombian Society of Architects in order to fulfill the realization of this project. The firm suggested a donation-driven model similar to the one used for their previous intervention in La Perseverancia. The Society, an institution that supports young architects, was quickly interested in joining the team. They brought in Equinorte, a formwork company that donated materials for the chapel´s construction. Additional donations from other companies such as Andemyc, Inacar, and Ferreteria Granada made the project´s completion possible.

CESCA, a student-collective organization, played an important role in the realization of the Colab 19´s proposal. Several CESCA members volunteered to help build parts of the chapel. In return, the students learned how to assemble horizontal formwork and use it as a design element in architectural compositions.  

Originally planned for 56 people, the chapel had an average occupancy of 80 people during Easter celebrations. After the chapel´s interior reached its maximum capacity, churchgoers settled into other spaces within the structure; some brought their own chairs and sat outside. The Santa Maria de la Alhambra church was successfully rehabilitated for the most important Christian dates of the year. 

This is the first public building in the world made with this horizontal system. The construction materials’ longevity and utility is intact after disassembly and a sustainable cycle is created.

In March 2020, the residents of Colombia’s capital faced the easter celebrations in isolation. For the senior community of the Alhambra Neighborhood, this meant disruptions to their leisurely routines, including attending mass for social interaction and mental health. To address this problematic, informal outdoor masses were held in a neighboring grocery store parking lot, reflecting the community's resilience and need for a congregation space.

Analyzing this need, Alsar-Atelier, in collaboration with other architects, donated the designs and fundraised a temporary open-air chapel. The project had significant logistical challenges since its inception, which led to the upscaling of  a rudimentary construction system—the horizontal formwork for concrete slabs. This allowed for swift assembly and disassembly, meeting the need for an ephemeral solution.

The resulting project managed to transform a parking lot into a religious temple for the duration of 4 days, incorporating elements of classical architecture in its plan form and atmosphere. This not only provided a sacred space for worship but also showcased the potential behind low-cost architectural solutions. During easter, the chapel was a focal point for the community, offering a space for leisure and social connection.

Its temporary nature minimized environmental impact, with materials later reused for their original purpose. The project's success highlights the importance of responsive and sustainable design in times of crisis, and since its inception the project has been recognized in various architecture publications for its innovation and community impact.
