The SISA seaplane base in Trieste seen from above

Aerial view of the Trieste waterfront around 1926 with the hangar of SISA, the Societa Italiana Servizi Aerei founded in the city in 1926 for seaplane connections. The large floating hangar bears the SISA lettering, while a seaplane rests beside the structure. Along the quays one can recognise steamers, boats and the seafront buildings. A record of the early years of Trieste commercial aviation.
