Five hot hours in Madrid between flights
Eight hours between flights in Madrid, about five of them usable: a hot walk from the Plaza de Oriente through old streets, a bear and a strawberry tree, and air-conditioned breaks.
Madrid was already properly hot when I emerged from the metro with only four or five useful hours before returning to the airport. I had visited the city several times before, so there was no reason to race through the standard checklist. The better idea was to wander and find what I had somehow missed on earlier visits.
My flight connection lasted about eight hours, but airport procedures and transport reduced the realistic time in the centre. It was still far too long to spend sitting at the terminal. The recorded temperature during the city window ranged from 27.4 to 36.9°C, with no rain; my less scientific impression was that it felt about five degrees hotter. Madrid carried on regardless, and in several places the crowds required almost as much negotiation as the heat.
From Plaza de Oriente into old Madrid
Plaza de Oriente gave me an obvious starting point. Its equestrian Philip IV is more technically interesting than it first looks: Pietro Tacca's horse rears with most of its weight carried at the back, a problem for which Galileo was consulted.
From there I moved around the Royal Palace and Almudena Cathedral. The two huge buildings face one another across Plaza de la Armería, producing the kind of monumental space that makes a short, unplanned walk rather efficient: there is a lot to look at without going very far.

I then followed the older centre eastwards. Plaza de la Villa was a useful reminder that Madrid is not only grand nineteenth- and twentieth-century avenues. Casa de Cisneros and the former Casa de la Villa frame a much smaller square around the monument to Álvaro de Bazán. A few minutes later I was inside Mercado de San Miguel. I stopped for a gourmet snack that was genuinely good and, considering the setting, reasonably priced. That made the market more than just an interesting food hall: for a hungry person, it was absolutely worth the small detour.

Plaza Mayor came next. The broad square, red façades and equestrian statue of Philip III gave me one of the clearest visual summaries of central Madrid. I kept walking without trying to fit every central Madrid landmark into the afternoon.
From there the route naturally pulled me towards Puerta del Sol. El Oso y el Madroño, the Bear and the Strawberry Tree, is one of those city symbols that is almost impossible to miss once you know what you are looking for. On Calle de Alcalá, looking above the crowd revealed the ornate Casino de Madrid.

Along Alcalá to El Retiro
Farther east, the Banco de España and Palacio de Cibeles made the transition from the old centre towards El Retiro feel almost continuous. The Banco de España clock and golden sphere are easy to overlook from street level; the much larger Palacio de Cibeles is not.
At El Retiro, the heat was shaping the walk as much as the route. The park gave the walk a different scale: wider paths, more trees and fewer stone façades, although certainly no shortage of people.

Leaving the park produced one final piece of Madrid eccentricity: a cow dressed for bullfighting outside Hotel Wellington. The hotel has a long association with bullfighters, which makes the sculpture slightly less random than it first appears, although only slightly.
Enough time to know it was not enough
After my final walk in Rio had left me upset by the homelessness I had seen there, Madrid felt unusually positive and alive. That was a personal contrast from two consecutive city walks, not a grand comparison between the cities. Madrid was simply full of movement, conversation and people, sometimes so many that the pavement became the obstacle.
On the way home from the Brazil trip, I had come into the centre for no better reason than avoiding an airport seat and finding a few things I had missed before. Four or five hours was enough to reinforce an inconvenient conclusion from my previous visits: even after being in Madrid a few times, I was nowhere near being able to say I had really seen it. The same is true of rather too many European cities. The problem is not finding things to see. It is finding somewhere to borrow the time.
