We arrived early in Lisboa at the city campsite and after a quick coffee/wifi break we jumped on the bus headed for the city centre with the intention of going on the cities Yellow Hop on/Hop off  tourist bus to figure out what attractions interested us. After arriving and purchasing a ticket we sat atop the open air bus exploring this wonderful city. The variety on offer was astounding as we drove past expansive gardens, monuments and buildings. The old buildings were in excellent condition and several were heritage listed while the new were artistic without being over the top.
