Why did Spain become a tourist kingdom?

First of all, the climate is suitable for tourism:

The central plateau of Spain has a continental climate, the northern and northwestern coasts have a maritime temperate climate, and the southern and southeastern parts have a Mediterranean subtropical climate. [6]

Spain's climate can be divided into the following parts:

Mediterranean climate: Eastern and southern Spain and most of the Canary Islands have subtropical climate.

Inland temperate continental climate: northern Spain is cold in winter (usually with snowfall) and hot in summer.

The temperate maritime climate of the North Atlantic coastal climate: the climate is warm in summer, and the rainfall is mainly concentrated in winter.

The northern and western coastal areas have abundant rainfall and humid climate, while most other areas have dry climate and serious water shortage. Annual precipitation: 800 mm in northwest coastal areas, 600 mm in central and eastern coastal areas and 300 mm in southern areas.

Secondly, there are many scenic spots. Spanish attractions:
