Valutazioni ex post degli interventi a Castellalto di Telve (TN) tra restauro e manutenzione

This paper presents an ex-post analysis of the effectiveness and durability of conservation interventions carried out at Castellalto di Telve (TN), including a critical assessment of maintenance activities undertaken by the municipality as part of evaluating restoration quality. Castellalto (818 m a.s.l.), a ruin protected under Italian Legislative Decree 42/2004, is privately owned and has been granted to the municipality under a thirty-year loan agreement since 2011, within a strategy aimed at its transmission to future generations. The first phase of works (2011-2015), funded at 80% by the Autonomous Province of Trento, concerned the Palazzo Nuovo and included structural consolidation, material analyses, and updated surveys. The second phase (2017-2020), co-funded at approximately 75% by the Local Action Group (GAL), focused on the Corte aperta ‒ Corte Nuova carriage passage, improving accessibility and public use of the site. A third phase, addressing the entire architectural complex, is currently awaiting funding. The interventions, based on conservative principles and preservation of existing structural balances, involved significant costs due to the wooded location and construction logistics. The case study highlights maintenance as the most critical phase of conservation in small mountain municipalities, where limited resources and operational constraints accelerate decay, as shown by the premature deterioration of the belvedere’s wooden decking, suggesting the need for more durable and easily maintainable solutions.
