ワルシャワラジオ塔（ポーランド語：Maszt radiowy w Konstantynowie）はかつてポーランドのマゾフシェ県プウォツク郡ゴンビンのコンスタンティヌフという集落にあった高さ646.38mの電波塔。1991年8月8日、支線の設置に伴う補修中の人為的ミスにより倒壊した。ブルジュ・ハリーファが建築中の2008年5月19日に649.7mに達するまで、人工建造物としては史上最高の記録を保持していた。
1970年7月に建造開始され、1974年5月18日に完成した。はしごとエレベーターを備えていたが、エレベーターで最上部に上るには30分を要した。自立型の塔ではなく、3角柱の鉄塔を3方向に設置された支線（ワイヤー）の張力で固定する方式（支線型）の塔であったが、補修中の作業ミスにより支線の張力のバランスが崩れて倒壊した。
It was in 1092 that this first Cathedral at Lincoln built by Bishop Remigius was consecrated. Remigius, a Benedictine monk was the first Norman Bishop of the largest diocese in medieval England, extending from the Humber to the Thames. The cathedral of this diocese had been at Dorchester, near Oxford, but in 1072 William instructed that the Bishopric should be moved to Lincoln.
A castle had already been established in Lincoln by William, located in the south-west corner of the old Roman upper city. The new cathedral was built of Lincolnshire oolitic limestone opposite the castle in the south-east corner.
In 1141, or possibly earlier, there was a fire which severely damaged the Cathedral. An earthquake caused structural damage to Lincoln Cathedral in 1185. St Hugh (Bishop of Lincoln, 1186-1200) began work on reconstructing the Cathedral in 1192. He used the Gothic style, where pointed arches, ribbed vaults and flying buttresses made it possible to make larger windows (for stained glass) and larger roof spans.
Between 1307 and 1311 the central tower was raised to its present height. Then around 1370 to 1400 the western towers were heightened. All three towers had spires until 1549 when the central tower’s spire blew down. It had been the tallest building in the world.
