His first attention was paid, most properly, to Havana. Already there had been constructed temporary fortifications at La Punta and El Morro, and also a camp more of observation than of defense at San Lazaro Cove, probably where the Queen's battery stood in later years. Both Captain-General Tejada and Antonelli were quick to see the importance of the Punta and Morro fortifications and to approve those headlands as the sites of the most powerful fortifications of Havana. Plans were accordingly made for extensive masonry forts at both those places, and these were approved and very prompt execution ordered by the King. Funds for the work were obtained from Mexico, from which source also appropriations were received for the maintenance of La Fuerza with its garrison of 300 men. The work of Antonelli in Cuba was by no means confined, however, to military engineering. He laid out and constructed a number of roads, including some which are to this day principal streets of Havana and its suburbs. He also constructed a dam across the Chorrera River and an aqueduct by means of which an ample water supply was conveyed to Havana and distributed through the city. For by this time it must be understood Havana was rapidly growing into a populous and prosperous community and was already the assured metropolis of the Island and indeed one of the three or four chief centres of Spanish civilization and authority in the western world. It was during the administration of Tejada that the technical legal title of "City" was conferred upon Havana, and the place received the grant of a coat-of-arms. Its escutcheon bore the emblems of a crown, underneath it in a blue field three silver fortresses, emblematic of La Fuerza, La Punta and El Morro, and finally a golden key symbolic of Havana's importance as the key of the western world. The administration of Tejada lasted a little more than five years and was marked with almost unbroken peace, prosperity and progress. The new fortifications of Havana were not all completed in that time, but they were carried far toward completion and the work upon them was marked with no such difficulties and complications as had been the bane of La Fuerza.
