Photogrammetry is an efficient discipline for documenting graphically and semantically cultural heritage. For decades, photogrammetric documentation following the 3x3 rules has been well-proved and used all over the world. However, when the data set is huge, the control, assessment and manage (e.g. labelling and recovery) of pictures is a crucial point in undefined or poorly structured archives. Furthermore, the digital era makes management of hundreds of pictures complicated because, on the one hand,there are many and big images and they require too much computer space (memory), and, on the other hand,there is no sense to hard-copy them by printing. Thus, this paper shows a way of labelling, retrieving and visualising efficiently digital images by means of multimedia packages, enabling easy and fast access through Internet. This paper reflects a new way of documenting, managing and visualising in a UNESCO World Heritage Monument,"La Lonja de los Mercaderes de Valencia", one of the most famous examples of European Gothic civil architecture.
