In the third week of June 2025 the first joint workshop between the La Silla and Las Campanas observatories was organised. Staff working in all principal areas took part, and over the two days we reviewed our shared mission alongside key differences in funding, operational models and data management. Presentations were offered by key people covering various aspects of operations, infrastructure and development plans, including upcoming instruments. The workshop aimed to foster collaboration and identify challenges for long-term sustainability, with specific areas of common interest such as safety, communications and light pollution.
