Abstract This article illustrates the results of a multidisciplinary study carried out in the ancient centre of Tropea in Calabria, southern Italy. The study has two main aspects: the inventory of valuable stone portals found on various historic buildings and an evaluation of their state of conservation. In the research 46 prestigious portals were examined, classified and mapped, and brief descriptions made of both stylistic typologies and peculiar characteristics typical to such ancient architectural features. Their state of conservation was evaluated on the basis of semi-quantitative indexes including visual observations and low impact mechanical tests in order to help understand how best to preserve them. The collected data contribute to an increase in the knowledge about the region’s built heritage and its continuing preservation, and provide a good starting point for further in-depth investigations.

意大利特罗佩亚古代中心的历史石门户：存量和保护状况

摘要本文说明了在意大利南部卡拉布里亚的特罗佩亚古代中心进行的一项多学科研究的结果。这项研究有两个主要方面：在各种历史建筑中发现的有价值的石头入口的清单，以及对其保护状态的评估。在这项研究中，对46个著名的门户进行了检查，分类和制图，并简要描述了此类古代建筑特征所特有的风格类型和独特特征。根据半定量指标（包括视觉观察和低冲击机械测试）对它们的保存状态进行了评估，以帮助了解如何最好地保存它们。收集的数据有助于增加对该地区的建筑遗产及其持续保存的了解，
