The Torre dels Vaïllos, a 16th-century historic building in Elche protected as a Site of Cultural Interest (BIC), has become a venue for open-air music events. Recently, during the Huerto Festival, promotional banners were placed on the tower's facade, including a luminous sign for a leisure venue, sparking a debate on the limits of commercial use of protected spaces and their conservation.

The criticism, mainly from Heritage experts, focuses not on the festival's development, which attracted hundreds of attendees, but on the Administration's use of the watchtower itself. Compromís has submitted a query to the local government seeking explanations regarding the municipal authorization granted to the leisure venue, which was one of the event's sponsors.

Two large promotional banners for the festival were unfurled, descending from the tower's top to almost the ground. According to the City Council, these textile supports were secured with mooring systems and weights, and no material damage has been reported. However, specialists remind that heritage protection should include preserving the image of protected assets, not just preventing physical deterioration.

The local government maintains that the installation did not physically affect the tower, as the banners were not anchored but attached to the balcony railing or held by weights. Nevertheless, doubts arise regarding the interpretation of Elche's Municipal Ordinance Regulating Advertising. Article 4 states that advertising activities are not permitted on properties declared BIC or of Local Relevance, although it includes an exception for elements that promote the building's historical-artistic character or identify activities taking place there.

Critics argue that this exception, which requires a favorable report from technical services, could be broadly interpreted, but they find it difficult to equate it with the installation of corporate advertising from companies unrelated to the building. The core issue is whether the advertising of a leisure venue falls under the definition of activities conducted on the premises.
