<a href="https://en.wikipedia.org/wiki/Spain">Source Wikipedia</a>
</p>
<p>
Spain (Spanish: España [esˈpaɲa] (About this sound listen)), officially the Kingdom of Spain (Spanish: Reino de España),[a][b]
is a sovereign state located on the Iberian Peninsula in southwestern Europe, with two large archipelagoes,
the Balearic Islands in the Mediterranean Sea and the Canary Islands off the North African Atlantic
coast, two cities, Ceuta and Melilla, in the North African mainland and several small islands in
the Alboran Sea near the Moroccan coast. The country's mainland is bordered to the south and east
by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast
by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic
Ocean. It is the only European country to have a border with an African country (Morocco)[h] and
its African territory accounts for nearly 5% of its population, mostly in the Canary Islands but
also in Ceuta and Melilla.

<h1>France</h1>
<p>
<a href="https://en.wikipedia.org/wiki/France">Source Wikipedia</a>
</p>
<p>
France (French IPA: [fʁɑ̃s]), officially the French Republic (French: République française [ʁepyblik fʁɑ̃sɛz]), is a country
whose territory consists of metropolitan France in western Europe, as well as several overseas regions
and territories.[XIII] The metropolitan area of France extends from the Mediterranean Sea to the
English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. The overseas territories
include French Guiana in South America and several islands in the Atlantic, Pacific and Indian oceans.
The country's 18 integral regions (5 of which are situated overseas) span a combined area of 643,801
square kilometres (248,573 sq mi) which, as of October 2017, has a population of 67.15 million people.[10]
France is a unitary semi-presidential republic with its capital in Paris, the country's largest city
and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille,
Nice, Toulouse and Bordeaux.

<h1>Portugal</h1>
<p>
<a href="https://en.wikipedia.org/wiki/Portugal">Source Wikipedia</a>
</p>
<p>
Portugal (Portuguese: [puɾtuˈɣaɫ]), officially the Portuguese Republic (Portuguese: República Portuguesa [ʁɛ'puβlikɐ puɾtu'ɣezɐ]),[note
1] is a sovereign state located on the Iberian Peninsula in southwestern Europe. It is the westernmost
country of mainland Europe, being bordered to the west and south by the Atlantic Ocean and to the
north and east by Spain. Its territory also includes the Atlantic archipelagos of the Azores and
Madeira, both autonomous regions with their own regional governments. At 1.7 million km2, its Exclusive
Economic Zone is the 3rd largest in the European Union and the 11th largest in the world.
