The Spanish Peninsula abounds in megalithic monuments. With the
exception of a few menhirs, whose purpose is uncertain, all are
sepulchral. Dolmens and corridor-tombs are numerous in many parts,
especially in the north-east provinces, in Galicia, in Andalusia, and,
above all, in Portugal. There is a fine dolmen in the Vall Gorguina in
North-East Spain. The cover-slab, measuring 10 feet by 8, is supported
by seven rough uprights with considerable spaces between them. In the
same region is a ruined dolmen surrounded by a circle nearly 90 feet in
circumference, consisting of seven large stones, some of which appear to
be partly worked. Circles are also found round dolmens in Andalusia.
Portugal abounds in fine dolmens both of the round and rectangular
types. At Fonte Coberta on the Douro stands a magnificent dolmen known
locally as the Moors' House. In the name of the field, Fonte Coberta,
there is doubtless an allusion to the belief that the dolmens conceal
springs of water, a belief also held in parts of Ireland.

At Eguilaz in the Basque provinces is a fine corridor-tomb, in which a
passage 20 feet long, roofed with flat slabs, leads to a rectangular
chamber 13 feet by 15 with an immense cover-slab nearly 20 feet in
length: the whole was covered with a mound of earth. The chamber
contained human bones and "lanceheads of stone and bronze." A famous
tomb of a similar type exists at Marcella in Algarve. The chamber is a
fine circle of upright slabs. It is paved with stones, and part of its
area is divided into two or perhaps three rectangular compartments. A
couple of orthostatic slabs form a sort of neck joining the circle to
the passage, which narrows as it leads away from the circle, and was
probably divided into two sections by a doorway whose side-posts still
remain.

In South-East Spain the brothers Siret have found corridor-tombs in
which the chamber is cut in the rock surface and roofed with slabs; the
entrance passage becomes a slope or a staircase. Here we have a parallel
to the Giants' Graves of Sardinia, which are built usually of stone
blocks on the surface, but occasionally are cut in the solid rock.
Other tombs in the same district show the common megalithic construction
consisting of a base course of upright slabs surmounted by several
courses of horizontal masonry (Fig. 14). The chamber is usually round,
and may have two or more niches in its circumference. It is
