This permanent fair, open every day of the week, has its origins in 1925, when a row of wooden booths of about 15 square meters was installed, which at the time had no light or heating and which, over the years, were replaced by others with more amenities, although similar in appearance to the original ones. The street connects the Paseo del Prado with the Retiro Park and is currently pedestrianized. It has an inclination of 6.9%. It is named after the Zamorano politician Claudio Moyano, whose statue is located at the start of the climb. At the end of the slope there is another statue dedicated to the Basque writer Pío Baroja. <span class="automatic-translation-warning">This text was automatically translated.</span>
