乌塔
石塔，高35米，8角、7层楼阁式。采取迭涩四跳出檐法，用赤泥作粘合原料。立面造型古朴典雅，线条优美。
塔基台为须弥座，座脚雕刻兽类、花卉，转角处有大若常人佛像。第一层塔身周长27.2米，墙厚3.4米，由下而上逐层缩小，顶层周长21.2米，墙厚2.6米。一、七两层一面开门、七面设龛，其余各层二面开门、六面设龛。
龛中共浮雕石佛像46尊，作工精美，是五代时期福建石雕艺术精品。五至七层塔壁上嵌有塔名碑、建塔记、祈福题名碑等。
塔内有折式阶梯，每层15级。塔外有环廊，廊沿设石栏杆、护板，塔刹饰铜制葫芦。
乌塔全称为崇妙保圣坚牢塔，在乌山路口和八一七路可看到，在乌山东麓，与于山的白塔互为犄角。因塔身为花岗岩青石所砌呈乌黑色，故称乌塔。
乌塔是唐贞元十五年(799年)，福建观察使柳冕为祝贺德宗李适寿诞祈福，用石头垒建的"贞元无垢净光塔"。塔身用青色花岗石砌造，外表略带乌黑，故名"乌塔"。现在乌山附近还保存着福州市至今最古的碑刻，碑的上头左右刻着六(虫离)，碑额题篆："贞元无垢净光塔铭"，记述当年柳冕建净光塔的情况。
五代时，王审知父子修复和创建了闽都七塔：乌塔、白塔、定慧塔、报恩塔、崇庆塔、开元塔、阿育王塔。宋景德元年(1004年)福州知州谢泌诗曰："城里三山千簇寺，夜间七塔万枝灯"。 闽都七塔现仅存乌塔与白塔。
清李家瑞《登无垢净光塔》诗说："石塔撑空立，登临至上层。眼穷千里远，梦想十年曾。" 杨庆琛《净光塔》诗句有："影如文笔依南涧，势作香台耸道山。插汉鸟窥天咫尺，旋空人与石回环。"
唐乾符六年(879年)，乌塔毁于黄巢入闽战乱之际。五代后晋天福六年(941年)，闽王王审知第七子王延福州乌塔 曦为自身及眷属、臣下祈福，在唐代净光塔遗址上兴建宝塔，叫道："崇妙保圣坚牢塔"。原计划造九层，但才建到七层时，王延曦就被部下所杀，还差两个月就完工的乌塔，就不再盖下去了。所以现存乌塔为八角七层，塔高35米。每层塔壁上设佛龛，嵌有浮雕佛像，共有四十六尊。这些花岗石浮雕佛像是五代时期福建雕塑艺术的代表作。四层、五层、七层，嵌有塔名碑、建塔塔记和祈福题名碑等。
该塔在鼓楼区乌石山东麓下殿里。前身为"无垢净光塔"，唐贞元十五年(799年)观察使柳冕建、庾承宣撰塔铭勒碑以志。乾符六年(879年)塔毁于兵，碑存。五代后晋天福六年(941年)，王延曦在净光塔遗址，用花岗石重建，名"崇妙保圣坚牢塔"。
明嘉靖年间，塔旁寺产因遭兵燹，久为民居，塔仅存。洪士英的《登塔寺》云："寺废塔犹存，经年不启门。邻梯间借上，石磴始能扪。鸡犬烟中市，桑麻雨外村。残碑虽剥蚀，仿佛是贞元。"清道光十八年(1838年)大风，塔身稍有倾斜。
民国时期，无人管理，曾因石栏板倒塌，死伤十余人。1957年政府拨款重修，采用混凝土灌浆，钢筋紧箍加固，在塔顶安装避雷器。"文化大革命"期间，塔上精美浮雕佛像被破坏。1978年重修，在塔周围设护围石栏杆，重建塔碑亭。亭内《敕贞元无垢净光塔铭》碑，是全国现存最早碑刻之一。
