Inside one of Portugal's most significant monuments, a collection of terracotta sculptures showcases the ingenuity of local craftsmanship, but climate change threatens their future survival.
Founded in 1153 by Portugal’s first king, Afonso Henriques, the Monastery of Alcobaça became an important center of Cistercian spirituality. In the late seventeenth and early eighteenth centuries, the Cistercian monks of Alcobaça, possibly with the help of hired outside artists, developed ingenious techniques to transform the region’s abundant clay into monumental religious sculptures. These sculptures were created in layers known as tacelos, fired at low temperatures, and then assembled in situ before undergoing surface finishing processes such as gilding and painting.
This method allowed for monumental scale, a high degree of detail, and harmonious integration with the monastery’s architecture. The sculptures’ expressive faces, dynamic gestures, and flowing garments and hair remain a testament to the artistic vision of their creators. These works are among the finest examples of baroque terracotta in the Iberian Peninsula, blending technical mastery with their intrinsic devotional purpose.

Vulnerability to Climate Change
The same qualities that make these sculptures extraordinary also render them vulnerable to contemporary climate changes. The low-temperature firing of the terracotta, their hollow interiors, and their layered construction make them fragile and especially susceptible to atmospheric changes. Prolonged exposure to humidity and temperature fluctuations has caused cracks, deformations, and material loss—and the level of deterioration continues to increase.

Heritage Conservation Meets Local Craft Traditions
Securing the future of these sculptures requires scientific research and preventive measures to halt further degradation. This also presents an opportunity to connect the conservation of this valuable heritage with the revitalization of local artisanal traditions. Terracotta production has long been a hallmark of the Alcobaça region, and preservation initiatives should engage the expertise of conservators while simultaneously renewing local interest and pride in the region’s ceramic production.

Joining the 2025 Watch
The status of the Monastery of Alcobaça as a UNESCO World Heritage site, which attracts up to half a million visitors annually, can also foster sustainable tourism that contributes to its preservation. This approach ensures the sculptures are safeguarded for future generations while supporting the regional economy.
The 2025 Watch highlights the Terracotta Sculptures of the Monastery of Alcobaça to support initiatives addressing climate challenges, advancing the knowledge of ceramic heritage conservation, and strengthening ties between the local community and this artistic legacy of universal value.
